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

${\left[{\mathrm{XeF}}_5\right]}^{-}$ has 2 lone pairs + 5 bond pairs = 7 hybrid orbitals

 $\Rightarrow {\mathrm{sp}}^3{\mathrm{d}}^3$hybridization with 2 lone pairs

$\Rightarrow$ Pentagonal planar.

 ${\mathrm{XeO}}_3{\mathrm{F}}_2$ has zero lone pairs + 5 bond pairs = 5 hybrid orbitals

 $\Rightarrow {\mathrm{sp}}^3\mathrm{d}$ hybridization

 $\Rightarrow$trigonal bypyramidal
