# How to make a phenyl radical with chemfig?

I'm trying to make a phenyl radical using chemfig, so far I've used this code:

\chemfig{*6(-\Lewis{0.,}=-=-=)}


What I obtain however is this, with a "broken" angle in the phenyl:

How to obtain a representation like this one?

I would propose to insert a small invisible bond:

\documentclass{article}
\usepackage{chemfig}
\begin{document}
\chemfig{*6(-(-[,.1,,,draw=none\Lewis{0.,})=-=-=)}
\end{document}


If you need it more often it is probably a good thing to define a suitable submol:

\documentclass{article}
\usepackage{chemfig}
\definesubmol{e}{-[,.1,,,draw=none]}
\begin{document}
\chemfig{*6(-(!e\Lewis{0.,})=-=-=)}
\end{document}


As for the scheme you can use chemfig's scheming commands (see “part V Reaction Schemes“ of the documentation).

Here is an example:

\documentclass{article}
\usepackage{chemfig}
\definesubmol{e}{-[,.1,,,draw=none]}
\begin{document}

\schemestart
\chemleft[
\chemfig{*6(=-=-(-Br)=-)}
\chemright]
% \arrow(from--to){->[<above>][<below>]}[<angle>,<length factor>]
\arrow(a--){->[$k_{f,1}$]}
% the \arrow is rather complex. all arguments are optional.
% In this case we name the preceding compound a' to be able to refer to it
% later.
\chemfig{*6(=-=-(!e\Lewis{0.,})=-)}
% the arrow type 0' is invisible but centers the phenyl' and the +':
\arrow{0}[,0]\+ Br$^-$
% now we insert the charge and the radical to the first compound, again using
% an invisible arrow and TikZ' anchors:
\arrow(@a.north east--){0}[,0] $-$\Lewis{0.,}
\schemestop

\end{document}

@pygabriel why did you unaccept the answer? –  cgnieder Jul 2 '12 at 10:37
thank you for pointing this! I probably misclicked it –  pygabriel Jul 2 '12 at 14:05
