### Should ClO2+ be trigonal planar?

Question: Should $\dpi{100} \fn_jvn ClO_{2}^{+}$ be slightly less than 120 degrees since there is a lone pair?

Answer: $\dpi{100} \fn_jvn ClO_{2}^{+}$ is a trigonal planar arrangement of electron density around the central Cl. However, the shape is bent. Therefore, yes, the bond angle is slightly less than 120 due to the lone pair.

The one lone pair of electrons (not shown in the figure) around the chlorine atom make the overall shape of ClO2+ to be bent.
