The state of hybridisations of cl in cationic and anionic parts in solid/liquid cl2o6 is?

Anionic form is=> ClO4- => the hybridization for Cl is => sp3 that is tetraderal as all the bonds formed are double bonded with O atom.
Cationic form is=> ClO2+ => sp2 hybridization that is Cl has one lone pair electrons with two doubly bonded O atoms.

Cl has 7 electrons.And molecule has negative charge so add one e–.than it becomes 8e–.there are 4 Oxygens makes double bonds.so lone pair is zero and sigma bonds are 4.So sp3 hybridisation
