How do I write $\ce{C_{2}{v}}$ properly in Latex so that the "2" and the "v" are both subscripted on the same subscript line? If I write it as $\ce{C_{2v}}$ (\ce{C_{2v}), I get an down-arrow symbol replacing the "v".

    $\begingroup$ The axis should be written in italic. Do not use the mhchem environment when not writing formulas - it is still actively developed and the might introduce new features, that ruin your intended layout. If you want non italics, use \mathrm instead. In you case, it should be written as $C_{\mathrm{2v}}. $\endgroup$ Commented Nov 5, 2014 at 14:24

Put an extra brace around the v: \ce{C_{2{v}}}
