`[Cu(NH_(3))_(4)]^(2+)` is paramagnetic and square planar complex. Justify. 

Geometrical isomerism in square planar complexes is given by

The hybridisation of metal ion in square planar complexes in

[PdBr_4]^(2-) is a sqaure planar complex. The hybridisation of Pd^(2+) is

Assertion: [Cu(en)_2]^(2+) is more stable than [Cu(NH_3)_4]^(2+) Reason: Both these complexes have a square planar shape.

Which complex has square planar structure?

[Cr(NH_(3))_(6)]^(3+) is paramagnetic while [Ni(CN)_(4))]^(2-) is diamagnetic Why ?
