Solution
[Ni(CN)4]2− Electronic configuration of Ni:[Ar]4s23d8 Electronic configuration of Ni2+:[Ar]4s03d8 Outer electronic configuration of Ni2+ (Refer Fig.1) Pairing of electrons takes place in the presence of strong field ligand CN− Thus,one 3d orbital becomes vacant.(Refer Fig.2) As the hybridization involved is dsp2,we get square planar complex.As there are no unpaired electrons the complex is diamagnetic.
