Math & Science ⇒ Typesetting a Line over Text

[hoytesara]

In my thesis I need to have a line over the formulas for some of my complexes to denote which atoms are coordinated to the metal, as shown in the above image. How do I go about typesetting this?

Hi,

welcome to the board!

You could use the mathtools package and the command \overbracket. For example:

Code: Select all

\documentclass{article}
\usepackage{mathtools}
\begin{document}
\[
    \overbracket{\text{Formula}}
\]
 \end{document}

You can adjust it by giving values to the optional arguments, the syntax is

\overbracket[line thickness][bracket height]{formula}

You could also misuse chemmacros' \redox command:

Code: Select all

\documentclass{article}
\usepackage{chemmacros}
\begin{document}

\ch{[\OX{a,Pt}(CH2)CH=CH\OX{b,C}(CH2)2(dppp)]}\redox(a,b){}

\end{document}

The \redox command suits perfectly. However, in order to make everything work properly, I had to modify things slightly. What I ended up going with was:

Code: Select all

\documentclass{article}
\usepackage{chemmacros}
\usepackage[version=3]{mhchem}
\usetikzlibrary{calc}
\begin{document}

\ce{[\OX{a,Pt}(CH2)CH=CH\OX{b,C}(CH2)2(dppp)]}\redox(a,b){}

\end{document}

Thanks!

Didn't it work without \usetikzlibrary{calc}? That would mean you must have an old (and obviously buggy) version of chemmacros.
