We recommend that you create all figures as vector-based graphics, such as those produced by Adobe Illustrator. Vector files can be properly resized without losing resolution，as they can be altered in size while maintaining high print-quality resolution. The symbols and words in the figures should be large enough to be clearly visible when the picture is reduced (reduced size is about 2 mm). We cannot accept files that are not readable by PowerPoint, Adobe Photoshop, Macromedia Freehand, or Adobe Illustrator. To keep file sizes reasonable, please save art at a resolution of 300 dots per inch (dpi) or higher for initial submission. Digital color art is best submitted in CMYK (cyan, magenta, yellow, black) rather than RGB (red, green, blue).

▲ Figures, schemes, and equations must be cited in the text and numbered in order of appearance with Arabic numerals.
▲ All graphics (including chemical structures) must be provided at the actual size that they are to appear (single-column width is 8.4 cm, double-column width is 17.7 cm). Please arrange schematics so that they fill the column space (either single or double), so as not to leave a lot of unused white space. Please ensure that all illustrations within a paper are consistent in type, quality, and size.
▲ Use capital letters for part labels in multipart figures – A, B, C, etc. These letters should be 9 pt and bold in figure. Place part labels at the upper left-hand corner of each figure part; if a part is an image, set labels inside the perimeter to aviod waste space.
▲ The symbols and words in the figures should be large enough to be clearly visible when the picture is reduced (reduced size is about 2 mm).
▲ Avoid using colors that are close in hue to identify different parts of a figure.

Note: The Chinese Journal of Structural Chemistry does not use charts, which should be converted into figures or schemes.

All tables should be cited in the text and numbered in order of appearance with Arabic numerals.
All table columns should have a brief explanatory heading and, where appropriate, units of measurement. Vertical lines should not be used. Footnotes to tables should be typed below the table and should be referred to by superscript letters. Each table should have a descriptive heading, which, together with the individual column headings, should make the table, as nearly as possible, self- explanatory. In setting up tabulations, authors are requested to keep in mind the column widths (8.4 cm and 17.7 cm), and to make the table conform to the limitations of these dimensions.

Graphical Abstract
Authors are required to provide a separate sheet containing a small diagram or other informative illustration (scheme or figure), showing the most important aspect of the paper. The words or sentences in the diagram must be concise. The height of the scheme or figure is 6 cm.

Figures of chemical structures
Figures of chemical structures should be drawn using ChemDraw according to the ACS-1996 standard as follows: chain angle, 120°; bond spacing, 18% of length; fixed length, 0.508 cm (14.4 pt); bold width, 0.071 cm (2.0 pt); line width, 0.021 cm (0.6 pt); margin width, 0.056 cm (1.6 pt); hash spacing, 0.088 cm (2.5 pt).

Curve graphics
Curve graphics should be drawn by Origin and their parameters are as follows: font, Arial; letter size, 8.0 pt; curve line width, 0.5 pt; symbol, 3.0 pt; width of graphics, 5.5 cm. The width of a picture will be 5.5 cm or 12.0 cm when printed. Use solid symbols for plotting data if possible (unless data overlap or there are multiple symbols). Line widths should be legible upon reduction (minimum of 0.5 pt at the final reduced size).

Figures of crystal structures
Figures of crystal structures should present all atomic labeling using Arial, a size of 7.5 pt with parentheses such as N(2), O(3), etc. If the table of the parameters of anisotropic displacements is not printed, at least one figure should show the displacement ellipsoids. Figures showing the crystal packing should not be overcrowded and should not show sections larger than necessary. Usually, one unit cell and a few adjacent atoms are sufficient. Include and label the outlines of the unit cell. Avoid the depiction of several translation-equivalent atoms in the viewing direction. If lines intersect, it should be clear which one is in front of the other.

Legends
Each figure and scheme should have a legend. In the final accepted manuscript, the legends should be listed together after the reference section of the text file and not be included with the drawings in the separate graphic files. Abbreviations, symbols, Nomenclature and units used in a figure should match those used in the text.

Tables
All tables must have a brief title and should only be subdivided by three horizontal lines (head rule, neck rule, and foot rule). Footnotes in the tables are denoted as superscripts by a, b, etc., and presented at the bottom of the table. Tables should be constructed using the table function in Word; do not make tables using the tabulator. Tables should be prepared to fit the page format of the journal (width of the columns is 8.55 cm; width of the pages is 17.6 cm). When a table consists mainly of graphic elements, the entire table should be prepared with Word DOC file rather than a drawing program. At this time, graphic elements linked to ChemDraw programs should be inserted to the table.

Symbols
Use only characters from the Symbol and Normal Text fonts, especially when inserting Greek letters and characters with umlauts, accents, tildes, etc.: α, ?, à, ?, ?. Symbols of physical quantities, stereochemical information (cis, Z, R, etc.), locants (N-methyl, α-amino), symmetry designations (C_2v) should be italicized. Chemical formulae should be numbered with boldface Arabic numerals (e.g., 1). If physical quantities are listed as numerical values without their units, e.g., in tables or for labels of axes in figures, the units must be specified after a slash or with a power of –1, e.g., T/K, c/(mol·L^–1). Abbreviations such as Me, Et, n-Bu, i-Pr, s-Bu, t-Bu and Ph may be used in formulae. General substituents should be indicated by R1, R² (not R₂, which means 2R) or R, R’. The spatial arrangement of the substituents should be indicated by hatched lines and a wedge. The Symbol font should be used for minus signs.

Abbreviations and acronyms
Abbreviations and acronyms should be used sparingly and consistently, following the system of abbreviations and symbols recommended by the International Union of Pure and Applied Chemistry. Where they first appear in the text, they should be defined (apart from the most common ones such as NMR, HPLC, and THF).

Nomenclature and units
Nomenclature must be consistent, clear, and unambiguous. Follow internationally accepted rules and conventions: use the international system of units (SI). If other quantities are mentioned, give their equivalent in SI or refer to IUPAC: Nomenclature of Organic Chemistry for further information.

Math formulae
Please submit math equations as editable text and not as images. Present simple formulae in line with normal text where possible and use the solidus (/) instead of a horizontal line for small fractional terms, e.g., X/Y. In principle, variables are to be presented in italics. Powers of e are often more conveniently denoted by exp. Number consecutively any equations that have to be displayed separately from the text (if referred to explicitly in the text).

Formulae, Equations and Schemes
Subscripts and especially superscripts should be written with care, and exponents should be arranged on a single line. Organic structural drawings should be submitted in a form suitable for direct photographic reproduction and should fill space economically. Do not use structures when a simple formula will suffice. Do not use multiple lines unnecessarily. Please type formulae and equations as normal text in the body of the text as far as possible.

Multiple-step reactions should be regarded as Schemes, and their reaction conditions should be given above the arrows rather than in the caption.

Footnotes
Footnotes should be used sparingly. Number them consecutively throughout the article. Many word processors can build footnotes into the text, and this feature may be used. Otherwise, please indicate the position of footnotes in the text and list the footnotes themselves separately at the end of the article. Do not include footnotes in the Reference list.

Formulae Analyses and Spectral Data
The physical and chemical parameters of new compounds should be given in the following order and style: m.p. 157–240 ℃, UV-vis (EtOH) λ_max: 238, 258 nm;  ¹H NMR (CDCl 3 , 300 MHz) δ: 0.78 (t, J = 8 Hz, 3H), 1.07 (d, J = 8 Hz, 3H), 2.96 (s, 1H), 3.80–4.00 (m, 1H), 6.90–7.10 (m, 1H); IR (KBr) ν: 3420, 3380, 1675, 1683, 1610, 1588, 1500l cm^-1; MS (70 eV) m/z (%): 525 (M⁺, 46), 507 (30), 43 (100). Anal. calcd. for C 12 H 11 N (%): C, 85.70; H, 6.55; N, 8.27. Found (%): C, 85.24; H, 6.56; N, 8.15 (HRMS calcd. for C 17 H 20 O 2 266.1458, found 266.1460). Note that the correct order of characterization data should be as follows: UV, NMR, IR, MS and elemental analysis.

Computer-aided image enhancement
Computer-aided image enhancement is often unavoidable. However, such manipulation cannot result in data that are less relevant or unrepresentative being shown and/or genuine and significant signals being lost. A clear relationship must remain between the original data and the electronic images that result from those data. If an image has been electronically modified, the form of the modification shall be given in the Figure caption. If computer-aided processing or modification of an image is a fundamental part of the experimental work, the form this processing takes must be clearly described in the Experimental Section.
