Math & Science ⇒ chemfig | Alignment of Atoms

Hello,

I've found that when putting a charged atom on position [6] the atom is not in line with the bond. It's slightly to the left. (Like the O- below the P).

Is there anything I can do about this? \hspace doesn't work. It puts the atom too far to the right.

Code: Select all

\documentclass{article}
\usepackage[T1]{fontenc}
\usepackage{graphicx}
\usepackage[margin=1in]{geometry}                
\usepackage{wrapfig}
\usepackage{chemfig}

\begin{document}
\Large{\chemfig{R-O-P(=[2]O)(-[6]O^{-})-O^{-}}}
\end{document}

Thank you

Hi,

very good minimal working example!

You can fix it by adding the superscript with \rlap:

Code: Select all

\Large{\chemfig{R-O-P(=[2]O)(-[6]O\rlap{${}^{-}$})-O^{-}}}

There is an easier fix using chemfig's "|" syntax, see section "Separating Atoms", page 28 of the manual:

Code: Select all

\documentclass{article}
\usepackage[T1]{fontenc}
\usepackage{graphicx}
\usepackage[margin=1in]{geometry}               
\usepackage{wrapfig}
\usepackage{chemfig}

\begin{document}
\Large{\chemfig{R-O-P(=[2]O)(-[6]O|^{-})-O^{-}}}
\end{document}

Thank you... That's great!
