Summary description: Draw molecules with easy syntax
Announcement text:
chemfig v1.83 * when `bond join=true`, bond joins between Cram-Cram and Simple-Cram bonds are improved * \polymerdelim macro is supported within the `\hreac...\endhreac` environment so that spaces in its arguments are preserved * manual is typeset using OpTEX * the English manual has been discontinued (hopefully only temporarily)
This package is located at https://mirrors.ctan.org/macros/generic/chemfig More information is at https://ctan.org/pkg/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.
