= C2h molecular point group
{c}
{title2=$C_{2h}$}

The <molecular point group> containing identity, one twofold rotation, an <inversion centre> and a mirror plane perpendicular to the twofold axis. Its four operations are $E,C_2,i,\sigma_h$. An extended anti conformation of <hexa-1,5-diyne> provides an example; changing the conformation can change the <symmetry>.
