Math & Science ⇒ mhchem | Problems with tricky Formulas

[jakethepeguk1]

Hello,

I have been using the mhchem package for doing chemistry notation and have found it really useful until i get to something which is slightly awkward to write.

Using the usual math mode way of doing subscripts and superscripts i want to write

$Sn_{1-x}^{4+}Sb_{x}^{5+}O_{2}^{2-}e_{x}$

however it doesnt look 'right'. The names of the atoms are italicised which i dont want.

Is it possible to write something similar to this with the mhchem package, which usually makes things so much easier and nicer to look at. Also when i try and write a simple equation with a subscript and superscript directly over each other as in

$Sn_{1-x}^{4+}$

with the mhchem package, the subscript and superscript are slightly staggered and not directly over each other.

I hope someone can help.

Thanks

PS. Im using version 3 of the mhchem package, with texlive 2011.

As far as I know, this is on purpose.

However, I couldn't verify this behaviour (see attached picture):

Code: Select all

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

$Sn_{1-x}^{4+}Sb_{x}^{5+}O_{2}^{2-}e_{x}$

\ce{Sn_{1-x}^4+Sb_x^5+O2^{2-}e_x}

\end{document}
