[NiCl_(2){P(C_(2)H_(5))_(2)(C_(6)H_(5))]_(2)] exibits temperature dependent magnetic behaviour (paramagnetic/diamangetic). The coordination geometries of Ni^(2+) in the paramagnetic and diamagnetic states are respectively

Answer»

tetrahedral and tetrahedral
SQUARE planar and square planar
tetrahedral and square planar
square planar and tetrahedral

Solution :In BOND states (paramagnetic and diamagnetic) of the GIVEN complex, Ni exists as `Ni^(2+)` whose electronic configuration is `[AR]3d^(8)4s^(0)`

In the above paramagnetic state the geometry of the complex is `sp^(3)` giving tetrahedral geometry.
the diamagnetic state is achieved by PAIRING of electrons in 3d orbital.

Thus the geometry of the complex will be `dsp^(2)` giving square planar geometry.
