Chemical structural Formulas

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.

Try chemfig. It is based on PGF/tikZ.
\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.
