These lonely pairs get excited when we impart the electric charge between them. Literature actually suggests $C_{3v}$ as the resulting distortion, but how would I know this when it isn't in the table? Log in to Wiley Online Library - Chemistry Europe Chem. On the other hand, $\ce{ClF6-}$ is octahedral simply because of electron correlation effects; the energy gained by distortion is insufficient.
