In how many of the following compounds 'd' orbital (which contains no nodal plane) is used in hybridisation of central atom/ion?

$\mathrm{Fe}(\mathrm{CO}{)}_5,{\mathrm{MnO}}_4^{-},\mathrm{Co}{\left({\mathrm{C}}_2{\mathrm{O}}_4\right)}_3^{-3}$

${\mathrm{NiCl}}_2{\left({\mathrm{PPh}}_3\right)}_2,{\mathrm{PtCl}}_4^{2-},\mathrm{Ni}(\mathrm{CN}{)}_4^{-2}$

$\mathrm{Ni}(\mathrm{CN}{)}_4^{-4}$
