GENERAL Articles suitable for publication in the journal Química Nova are those written in Portuguese, English or Spanish and that cover the traditional fields of chemistry, as well as articles on chemical education, the history of chemistry, science policy, etc., besides articles on related fields, as long as they have a substantial chemical content. Articles should conform to one of the categories below:
Original Articles: for communicating original research. Articles should follow the usual form of presentation, including introduction, results, experimental section, etc., as appropriate for the work being submitted. They should have a maximum of 25 pages, including figures, tables, diagrams, etc. All pages should be numbered.
Articles on Education: for communicating research on the teaching of chemistry and for disseminating innovative experiments in undergraduate and post-graduate teaching. They should have a maximum of 25 pages, including figures, tables, diagrams, etc. All pages should be numbered.
Technical Notes: for communicating methods, techniques, equipment and accessories developed in the author's laboratory, as long as they have a substantial chemical content. They should have a maximum of 25 pages, including figures, tables, diagrams, etc. All pages should be numbered.
General Subjects: subjects of general interest for chemists, such as science policy, undergraduate and post-graduate programs, history of chemistry, etc. They should have a maximum of 40 pages, including figures, tables, diagrams, etc. All pages should be numbered.
Review Articles: for communicating progress in a specific field of chemistry, with the objective of providing a critical account of the state of the art from the point of view of the highly qualified and experienced specialist. They should have a maximum of 40 pages, including figures, tables, diagrams, etc. All pages should be numbered.
It is essential for authors to have publications in the field reviewed attesting their experience and qualification. Before submitting the manuscript, authors should send an e-mail to the editors with an abstract of the review and a letter explaining the relevance of the publication. The material will be examined by the editors and, once approved, authors will be requested to submit the full manuscript, according to QN guidelines. This manuscript will then be submitted to referees to be evaluated. Acceptance of submission does not guarantee publication of the final manuscript.
The editorial board of QN may occasionally invite qualified researchers to submit a review article.
PRIOR TO THE SUBMISSION
Copyright Licence
The submission of a manuscript implies that it has not been previously published, that it is not under consideration for publication elsewhere or that it will not be simultaneously published elsewhere in the same format without the written permission of the Editors. Additionally, it implies that the submitting author has the consent of all authors. By submitting a manuscript, the authors agree that their paper's copyright is transferred to the Brazilian Chemical Society (Sociedade Brasileira de Química, SBQ) if and when the manuscript is accepted for publication. Accepted manuscripts and illustrations become the property of the SBQ.
Manuscript Organization
Authors should present their materials with the utmost conciseness and clarity. The Introduction should clearly and briefly identify, with relevant references, both the nature of the problem under investigation and its background. Extensive reviews of the literature cannot be accepted. In Articles, the Experimental section may precede or follow the Results and Discussion section, but should be separated from it. The addition of a final section at the end of the manuscript, which briefly summarizes the main Conclusions of the work, is recommended and needs to be just after the Results and Discussion section. Descriptions of experiments should be given in sufficient details to enable other researchers to repeat them. The degree of purity of materials should be given, as well as all quantities used. Descriptions of established procedures are unnecessary. Standard techniques and methods used throughout the work should be stated at the beginning of the section in a Materials and/or Methods subsection, in the Experimental section. Apparatus should be described only if it is non-standard. Commercially available instruments should be referred to by their suppliers and models. All new compounds should be fully characterized, which includes spectroscopic data and elemental analyses. High-resolution mass spectra may substitute for elemental analyses if accompanied by unequivocal proof of sample purity (melting points, copies of NMR spectra, etc.). For compounds prepared in enantiomerically pure or enantiomerically enriched form, specific optical rotation must be given. In cases where enantiomeric excess is determined by chromatographic and/or spectroscopic techniques, copies of the appropriate chromatograms and/or spectra should be included as Supplementary Material upon submission of the manuscript. Data associated with specific compounds should be listed after the name of the compound concerned, followed by the description of the preparation, or else presented in tabular form in the Results and Discussion section. All spectra must be included in the Supplementary Material (SM, see Supplementary Material section). Many theoretical and computational papers use a routine procedure based on a well-documented method, being it semi-empirical or ab initio. It is then sufficient to name the particular variant, referring to key papers, in which the method has been developed, to cite the computer program used and to indicate briefly any modification made by the author. Complementary data meant to support the analysis of Communications should be included as SI. It is the authors' responsibility to obtain permission from other publishers for the reproduction of artwork from other journals in the reviews or in any other type of publication. Such specific Copyright Permissions should be sent to the Química Nova Editorial Board. Suitable acknowledgement of reproduction must be given in the captions.
Manuscripts written in English considered to further evaluation are expected to come along with a statement from a specialized company (or person), attesting that the text was submitted to formal English review (should be sent to sbqedit@sbq.org.br together with the revised version of the manuscript). Otherwise, the Editor can, at any time, ask for such procedure to warrant the English precision, conciseness and understanding of the manuscript.

Details:
First Page
- Graphical Abstract (see Graphical Abstract section)
- Title
- Authors' names: full given name, followed by the middle name initial(s) and then by the full last name. An asterisk (*) should follow the name of the corresponding author.
- Addresses: Authors are asked to provide full addresses for correspondence. The e-mail address of the corresponding author should be given as a footnote. If the address where the work was carried out is different from the present address of any of the authors, a footnote indicating the current position can be included. Each address should have a correspondent letter. As for instance:
Jailson B. de Andrade*,a and Marta V. Andradeb
Second Page
- Abstract (in English): maximum of 200 words.
- Keywords: a minimum of three and maximum of five. Broad-sense words such as "water" should be avoided.
Third Page On
The text should start from the third page of the manuscript.
Attention: all nomenclature should be consistent, clear, unambiguous and in accordance with the nomenclature rules established by the IUPAC, the International Union of Biochemistry, the Abstracts Service, the Nomenclature Committee of the American Chemical Society or any other appropriate bodies. Units and symbols should follow IUPAC recommendations. Authors will not be denied any reasonable usage, but if non-SI units are used for critical data or for quantities measured to a high degree of accuracy, final numerical values should also be expressed in SI units. Be sure that all abbreviations are once specified (as near as possible of their first citation).
The author should be aware of the following guidelines:
All units must be separated from the respective values using a single space (including degree Celsius). The same rule should be applied to units in sequence.
Examples:
10 ºC;
15 mg L-1 (avoid mg/L);
10 m s-2 (avoid m/s2);
Guidelines for graphical elements and tables
General Size
The authors should think about the illustration size for double column (172 mm) of the journal. But, the font type size of text must be consistent with the illustration since it can be reduced during preparation of the Galley Proof.
This is important when choosing symbols for graphics, drawings, charts, photos, etc., be consistent, make your manuscript look nicer: use the same size and same font type in graphics, schemes, etc.
Graphs and Figures
Lines and Lettering: Lines should be black and of an adequate and even thickness. Solid, broke, dotted and dot-dash lines should be used in graphics. Particular care should be taken to ensure that the lines in a spectrum are of adequate thickness.
Lettering should not be smaller than 7 pt (Times New Roman) and lines not thinner than 0.5 pt. Lettering and lines should be of uniform density throughout the figures.
Labeled atoms in ORTEP (or any other) diagrams should have atom numbers in parenthesis, e.g., Fe(1), C(44).
Symbols representing physical quantities should be given in italics, e.g., J (Hz), δ (ppm), m/z, etc.
Graphs
Scales: graphs should have only the minimum necessary scale divisions marked by numerals.
Axis labels should use SI units, separated from quantities.
For graphs, use slashes in X and Y axes to separate axes names from units. For example: 2θ / degree; Temperature / ºC; time / min; Size range / mm; Wavenumber / cm-1. Use parentheses only to group a set of units, e.g., Concentration / (mol L-1) ; 103 (T/K)-1, etc.
Pay close attention to the way decimal values are expressed in English. Employ dots instead of commas.
Figures must have a high quality in order to be well reproduced. Use high resolution. If necessary, resize to a smaller size to get higher quality.
Curves should be labeled (a), (b), (c) etc. and further information be given in the figure legend/caption.
Data Points must be shown sufficiently large to be distinguishable. Whenever possible, they should be marked with the following symbols (use alternated full and open symbols): ●, ○, ■, □, ▲, Δ, ♦ , ♢
Graphs/Figures should be pasted from their original files (Origin, ChemDraw, Corel etc.) and have an excellent quality. If you have to digitalize (scan) the figures (photos, for instance), choose the following scan options: black & white (B&W), no background and minimum of 300 dpi. If you wish them to be published online in color, send both the colored and B&W versions to the Editorial Office, matching the captions of the figures to accommodate the alternatives.
For computer-generated artwork, background or shadings should be avoided.
Structural Formulae
Figures, schemes and structures should be drawn to fit single or double-column widths. They should look proportional in case they are reduced.
Structures should be numbered with bold Arabic numerals, e.g. 1, 2.
All chemical structures included in the manuscript should be drawn using the same letter type (Times New Roman or Arial), size of cyclic groups, size and thickness of chemical bonds, and, the most important, authors should use the same standard throughout the work, including all figures, schemes, etc.
The following organic group abbreviations may be used: Me, Et, nPr, nBu, sBu, tBu, Ph, CO2R, CO2H, iPrOH.
One variable univalent substituent is indicated by R. When more than one independent variable general substituent is present, R1, R2, R3, etc. should be used.
A variable metal may be indicated by M and variable ligands by L1, L2, L3 or L1, L2, L3, etc.
Photographs
Photographs should be highly contrasted, positive and not mounted.
When necessary, the scale should be drawn on the photograph itself and not below.
Color prints are rarely reproduced satisfactorily in black and white. Original B&W photographs are preferred to report experimental results, such as electron micrographs or to illustrate special equipment adaptations.
Tables, Data and Units
Tables
Format your table to give straightforward information to the reader. Do not use shades or bold lettering. Indicate any extra information as a footnote with letters, e.g., a, b, c, etc.
Data
For negative numbers, ions and equations in text and tables use − (negative symbol) instead of - (hyphen). Examples: Cl−, −0.40, y = ax − b.
Units
Use International System Units (SI), e.g., m, s, kg, Pa, mol L-1, etc, separated from quantities with a blank space. Example: 300 K, not 300K.
Molar (M) is no longer a valid concentration expression for IUPAC; it is suggested mol L-1 or mol dm-3, but be consistent throughout your manuscript.
Graphical Abstract (GA)
The figure should summarize the content of the manuscript in a concise, pictorial form, designed to capture the attention of a wide readership. The author should present a new figure, using as an idea a key structure, a reaction, an equation, a concept, a graphic, a theorem, etc. It should use colors as much as possible and have an artistic and imaginative idea. It is not acceptable photos of commercial equipment in GA or in the text of the manuscripts.
Pay Attention: the image should have high resolution (*.tiff / *.jpg or any other image file that can be edited) and be 8 cm wide and 4 cm high [the text elements inside the image should be readable on these dimensions]. Along with the GA figure, insert a short explanatory text about it below (three lines at the most).
Therefore, be smart to advertise your manuscript: send a beautiful and appealing graphical image.
Guidelines for citations and reference list
Graphical elements and tables should be numbered and cited in text using the first letter uppercase. One should not abbreviate their titles.
Examples:
... as seen on Figure 1. (do not use Fig. 1)
Table 2 shows the obtained results. (do not use Tab. 2)
Reference numbers in the text should be typed consecutively as superscripts after punctuation, without parentheses or brackets.
Examples:
sodium salicylate,1-3
Nishide et al.,4
by reduction of chromic acid.4-8,12
The cited literature should be listed on a separate REFERENCES section, in the same order it appears in the text. The journal title abbreviations should match the Chemical Abstracts Service Source Index (http://cassi.cas.org).

Manuscripts including crystallographic data
Deposition of crystallographic data
Prior to the submission of the typescript including crystallographic data, the author(s) should deposit, in the relevant Data Center, the data corresponding to each structure to be reported.
Data for organometallic, organic and coordination (Werner-type) compounds should be sent to the Cambridge Crystallographic Data Center (CCDC) by e-mail, in CIF format. More information and a checklist of data items to be included in the deposit can be obtained from the CCDC homepage: http://www.ccdc.cam.ac.uk/.
Data for inorganic compounds should be sent to Fachinformationszentrum Karlsruhe (FIZ) by e-mail:crysdata@FIZ-Karlsruhe.de.
Deposition Codes
The Data Centers will provide deposition codes for each data set, which should be quoted in the typescript under a Supplementary Material heading after the Conclusions.
Standard text for CCDC:
Crystallographic data (excluding structure factors) for the structures in this work were deposited in the Cambridge Crystallographic Data Centre as supplementary publication number CCDC XXXXXX. Copies of the data can be obtained, free of charge, via www.ccdc.cam.ac.uk/conts/retrieving.html or from the Cambridge Crystallographic Data Centre, CCDC, 12 Union Road, Cambridge CB2 1EZ, UK; fax: +44 1223 336033. E-mail: deposit@ccdc.cam.ac.uk.
Preparation of Crystallographic Material
- When the manuscript is submitted, the following guidelines should be observed:
The Abstract should not contain crystal data, but a concise statement of the main features of the structural results.
The following crystallographic data should be given in a paragraph of a Table, in a concise format:
- Color, habit and size of the crystal(s) used, behavior of the compound under the data collection conditions.
- The chemical formula should correspond to the complete chemical unit encompassing the crystallographic symmetry, the formula weight, F(000), the absorption coefficient and the measured and calculated densities.
- The unit cell parameters with esd's and the X-ray wavelength used.
- The crystal system, space group and number of chemical units per cell.
- Type of diffractometer used and method of data collection, total number of data collected, number of unique reflections, R(int) value, number of observed reflections with cut-off parameter, use or not of absorption correction, transmission factors.
- The final results: R, wR, S and the number of parameters refined; treatment of hydrogen atoms; final peak and hole in the last difference map. Only refinements on F2 will be accepted.
Discussion of the Structure
It must include a labeled diagram of the structure, a list of relevant geometric parameters - interatomic bond distances and angles, torsion angles, hydrogen bond parameters, etc. Data of less important parts of the structure, such as ligand sub-groups (phenyl rings, etc.) should be omitted.
Manuscripts including NMR, IR, mass spectra, etc.
Whenever a compound is synthesized or identified (new or already known), it is imperative to send all spectral data (data and spectra) as Supplementary Material (see Supplementary Material section) along with your submission, at the end of your PDF file.
A brief mention to the existence of complementary data should be included in the Supplementary Information topic after the CONCLUSIONS section.
Supplementary Material (SM)
This resource was created so that the printed version of the manuscript would contain only the strictly necessary number of figures and tables. The material should be of good graphical quality and be placed at the end of the manuscript, in the same file. Whenever the SM is present, a section named SUPPLEMENTARY MATERIAL should be created, right after CONCLUSIONS, describing its content. The text should also indicate the free access to the MS at Química Nova website (http://quimicanova.sbq.org.br). Graphical elements and Tables of SM should be sequentially numbered, with the letter S after numbering, e.g. Figure 1S, Figure 2S, Table 1S, Table 2S, etc.
The SM is a separate document. It should have its own reference list, if necessary. Editors, at any time of the editing process, may ask authors to split off part of the manuscript, presenting it as SM.
When submitting
QN provides on-line submission which can be accessed through a login and a password. It is possible to register on our home page (http://quimicanova.sbq.org.br) using the option New User. After having registered, authors can easily follow on-screen instructions. The submission of a single file of the complete manuscript in .pdf format is requested. A tool is available for generating a .pdf file from .doc or .rtf files, with automatic transmission to the author's e-mail. As soon as submission is completed, the system will inform automatically by e-mail a temporary number for the manuscript. After the submission has been checked by the editors, another e-mail will be sent with the final manuscript reference code.
If the e-mail with the temporary reference number is not received, submission of the article has not been completed and authors have a maximum of 5 (five) days to complete it. Thereafter the system does not allow submitting the manuscript and the process has to be started over again.
Authors can follow the status of manuscripts directly through the system.
On submitting an article, an accompanying letter is requested, which should be typed in the appropriate space provided on the electronic form. In this letter, the e-mails of all authors must be given. Also, the names, affiliation and e-mails of three or four prospective referees, which should not belong to the same institution(s) as the authors, should be given.
Evaluation versions
A single .pdf-document, including the supplementary material, should be submitted. The online system do not accept other formats at that stage.
Revised manuscripts: Manuscripts returned to authors for revision should be sent back to the editors within thirty days. Thereafter they will be considered withdrawn and the system will close the process, not allowing it to be reopened. In this case, the article has to be resubmitted, starting a new process.
The revised manuscript should be submitted by the author who originally submitted the article, using the same login and password. On-screen instructions should be followed for sending the complete .pdf-document of the revised version, as well as for answering the referees' comments (also in .pdf), detailing changes made in the new version and, in case some of the referees' suggestions were not accepted, justifying the reason for this. The two files should be sent using the link Revised Version on the Author's Home page of the on-line submission system of QN.
As soon as submission is completed, the system will inform automatically by e-mail a temporary number for the manuscript. After the submission has been checked by the editors, another e-mail will be sent with the final manuscript reference code.
If the e-mail with the temporary reference number is not received, submission of the article has not been completed and authors have a maximum of 5 (five) days to complete it. Thereafter the system does not allow submitting the manuscript and the process has to be started over again.
Authors can follow the status of manuscripts directly through the system.
Final version
At the time the final version is requested, authors will receive specific instructions regarding programs to be used for preparing text, figures, tables, etc. Files in .pdf-format will then no longer be asked for, the authors should send .doc or .docx files instead. The graphical elements and tables should be sent separately, in their original formats:
Structures in: *.cdx (ChemDraw or ISIS-DRAW);
Graphics in: *.opj/org (Origin); *.xls/xlsx (MS Excel);
Tables in *.doc (MS Word); *.xls/xlsx (MS Excel);
Others possible formats: *.cdr, *eps (CorelDraw, Adobe Illustrator, etc.);
The editors of QN reserve the right to make small changes to the manuscript, if necessary, to adjust them to the norms of the Journal or improve the style, respecting naturally the content of the article. Whatever the nature of the manuscript, it should be original in terms of methodology, information, interpretation or critique. The quality of the article will be attested by two referees, indicated by the editors.
