What is the hybridization of interhalogen compounds of the type ${{\mathrm{XX}}^{,}}_5$ (Square pyramidal)

Explantion: The structure of all interhalogen compounds of the type ${{\mathrm{XX}}^{,}}_5$ involves ${\mathrm{sp}}^3{\mathrm{d}}^2$ hybridization of the central halogen atom X and hence have octahedral (also called square pyramidal) geometry and with one position occupied by a lone pair.
