I use \newcommand{\bondwidth}{0.06642 em} and \setbondstyle{line width = \bondwidth} to make my bonds a bit thicker, however, this doesn't seem to affect aromatic rings, leading to a slightly irritating mismatch.

Current Look

I'd like to make the width match that of my lines, preferably with some kind of global configuration setting.

Any suggestions?


You should use the \setchemfig{} command as describe in the notice p.4

\setchemfig{chemfig style={line width=.25pt}}


enter image description here

You could also use

\chemfig{-[:0]**[,,line width=.25pt]6(---(-)---)}

line width controls the thickness of the circle.

  • I tried adding \setchemfig{chemfig style={line width=\bondwidth}} however I still end up with the image seen in my original post. I imagine the aromatic ring's thickness needs to be set differently. – tecosaur Oct 31 '18 at 5:44
  • Did you update your distribution ? – GézàLaTeX Oct 31 '18 at 7:03
  • I'm not quite sure what you mean. I'm using TeX Live 2018. – tecosaur Oct 31 '18 at 7:05
  • The package is perhaps outdated. You could update thé package chemig with the Package Manager or use a command prompt and write sudo tlmgr update --all if your OS is Linux. – GézàLaTeX Oct 31 '18 at 7:41
  • I was using chemfig v1.31, I updates to 1.32 and that fixed it :) – tecosaur Oct 31 '18 at 14:35
