$[NiCl_4]^{2-}$

Vedclass · Answer

(D) The geometry of coordination complexes depends on the nature of the ligand and the central metal ion. $1$. $[NiCl_4]^{2-}$: $Ni^{2+}$ has a $d^8$ configuration. $Cl^-$ is a weak field ligand,so it does not cause pairing of electrons. The hybridization is $sp^3$,resulting in a tetrahedral geometry. $2$. $[PdCl_4]^{2-}$,$[Ni(CN)_4]^{2-}$,and $[Pd(CN)_4]^{2-}$: These complexes involve $Pd^{2+}$ or strong field ligands like $CN^-$,which cause pairing of electrons. They undergo $dsp^2$ hybridization,resulting in a square planar geometry.
