Question

A list of species having the formula $X{Z}_4$ is given below. $Xe{F}_4,S{F}_4,Si{F}_4,B{F}_4^{-},Br{F}_4^{-},{\left(\left[Cu{\left(N{H}_3\right)}_4\right]\right)}^{2+}$, and ${\left(\left[FeC{l}_4\right]\right)}^{2-},{\left(\left[CoC{l}_4\right]\right)}^{2-}$
${\left[PtC{l}_4\right]}^{2-}$
Defining shape on the basis of the location of $X$ and $Z$ atoms, the total number of species having a square planar shape is
