Summary description: Draw molecules with easy syntax
Announcement text:
- tikZ instructions are saved to a file when “save” key is true - bugfix: “arrow head,” “arrow style,” and “arrow coeff” keys are correctly handled in hreac environment - bugfix: any type of arrow defined by \definarrow is allowed in hreac environment - bugfix: inconsistent behavior of <style> when an arrow “!@<name>[<style>]--!” is drawn in \schemestart environment
The package’s Catalogue entry can be viewed at https://ctan.org/pkg/chemfig The package’s files themselves can be inspected at https://mirrors.ctan.org/macros/generic/chemfig/

Chemfig – Draw molecules with easy syntax
The package provides the command \chemfig{<code>}, which draws molecules using the TikZ package. The <code> argument provides instructions for the drawing operation.
While the diagrams produced are essentially 2-dimensional, the package supports many of the conventional notations for illustrating the 3-dimensional layout of a molecule.
The package uses TikZ for its actual drawing operations.
