LaTeX forum ⇒ Graphics, Figures & Tables ⇒ Chemical structural Formulas Topic is solved

[MatthiasN]

Hi everyone,

I was wondering if there is a package for the drawing of chemical formulas. I am currently using mhchem but this only allows the user to write the formula, but not to draw the structure of the molecule. So there is no misunderstanding I attached a picture that shows what I would like to be able to do.


Thanks for reading,
Matthias

Try chemfig. It is based on PGF/tikZ.

Code: [Select all] [Expand/Collapse] [Download] (untitled.tex)

\documentclass{article}
\usepackage[T1]{fontenc}
\usepackage{chemfig}
 
\setdoublesep{0.35700 em}  % 'Bond Spacing'
\setatomsep{1.78500 em}    % 'Fixed Length'
\setbondoffset{0.18265 em} % 'Margin Width'
\newcommand{\bondwidth}{0.06642 em} % 'Line Width'
\setbondstyle{line width = \bondwidth}
 
\begin{document}
   \chemfig{*6(=(-NO_2)-=-(-CH_3)=-)}
\end{document}

For detailed descriptions of the capabilities and usage please refer to the package manual. You may combine the package with the very useful chemmacros.

Looks really neat and since I am currently trying to work my way through the tikz manual, I think it can be really beneficial that it is based on tikz.

Thanks for your help!
