${\text{XeF}}_{\text{4}}\text{+}{\text{SbF}}_{\text{5}}\to {\text{[XeF}}_{\text{3}}\text{]}\text{+}{{\text{[SbF}}_{\text{6}}\text{]}}^{-}\to \underset{\underset{\text{T-Shaped}}{{\text{sp}}^{\text{3}}\text{d}}}{{{\text{[XeF}}_{\text{3}}\text{]}}^{\text{+}}}\text{+}\underset{\underset{\text{octahedral}}{{\text{sp}}^{\text{3}}{\text{d}}^{\text{2}}}}{{{\text{[SbF}}_{\text{6}}\text{]}}^{-}}$
As$[\mathrm{X}\mathrm{e}{\mathrm{F}}_3{]}^{+}$has 3 bond pair and 2 lone pair of electron so it has$\mathrm{s}{\mathrm{p}}^3\mathrm{d}$hybridisation and T-shape.
$[\mathrm{S}\mathrm{b}{\mathrm{F}}_6{]}^{-}$has 6 bond pair electrons so it is$\mathrm{s}{\mathrm{p}}^3{\mathrm{d}}^2$hybridise and octahedral in shape.
