NiCl 2 {P(C 2 H 5 ) 2 (C 6 H 5 )} 2 exhibits temperature dependent magnetic behaviour (paramagnetic/ diamagnetic). The coordination geometries of Ni 2+ in the paramagnetic and diamagnetic states are respectively
Text Solution
Verified by ExpertsThe correct answer is:
C
[NiCl 2 {PEt 2 Ph}] contains Ni 2+ with electronic configuration
Ni 2+ = [Ar] 3d 8 4s 0 
In high spin state, it is paramagnetic, sp 3 hybridised, tetrahedral.
In low spin state, it is diamagnetic, dsp 2 , square planar.
