Answer
4
Explanation
$\mathrm{XeF}_4, \mathrm{BrF}_4^{-},\left[\mathrm{Cu}\left(\mathrm{NH}_3\right)_4\right]^{2+},\left[\mathrm{PtCl}_4\right]^{2-}$ are square planar as shown below :
$\mathrm{SF}_4(\mathrm{See}-\mathrm{saw})$ as shown below:
$\mathrm{SiF}_4, \mathrm{BF}_4^{-},\left[\mathrm{FeCl}_4\right]^{2-},\left[\mathrm{CoCl}_4\right]^{2-}$ are tetrahedral as shown below :
$\mathrm{SF}_4(\mathrm{See}-\mathrm{saw})$ as shown below:
