In the given complex , NiCI₂{P(C₂H₅)₂(C₆H₅)}₂ nickel is in + 2 oxidation state and the ground state electronic configuration of Ni²⁺ ion in free gaseous state is

For the given four coordinated complex to be paramagnetic , it must possess unpaired electrons in the valence shell. To satisfy this condition, four lone pairs from the four ligands occupies the four sp³ hybrid orbitals as

There fore , geometry of paramagnetic complex must be tetrahedral. On the other hand , for complex to be diamagnetic, there should not be any unpaired electrons in the valence shell. This condition can be fullfilled by pairing electrons of 3d orbitals against Hund's rule as

The above electronic arrangement gives dsp² hybridisation and therefore, square planar geometry of the complex.
