# Multiple bonds in Lewis structure

I've been using the chemfig package for drawing Lewis structures but have run into an issue in which I need to show multiple bonds between two atoms in Lewis dot notation as show below.

The code I have so far is:

\lewis{0:,H} \lewis{0:,C} \lewis{4:,C} \lewis{4:,H}


which produces

Is this structure possible with the chemfig or other package?

It seems that \lewis introduced some negative spaces that need to be compensated. And one can cheat with \vphantom.

• “ It seems that \lewis introduced some negative spaces” there is also \Lewis which doesn't ignore its bounding box. – clemens Aug 1 '18 at 7:16
