The shape/structure of ${\left[{\mathrm{XeF}}_5\right]}^{-}$and ${\mathrm{XeO}}_3{\mathrm{F}}_2,$ respectively are :

(i) ${{\mathrm{XeF}}_5}^{-}$St. no. = Bond pair+ Lone Pair
                                  =(5+2)=7
                         So, hybridization is = And structure is pentagonal planar.
(ii) ${\mathrm{XeO}}_3{\mathrm{F}}_2$St. no. =5
                         So, hybridization is = sp³d
                         And structure is trigonal  bipyramidal..
