Which of the following statement is not correct for [Ni(CN)_(4)]^(2-) and [NiCl_(4)]^(2-) complexes.

Answer»

Both have Niin + II oxidationstate.
`[NiCl_(4)]^(2-)` is a low spin while `[Ni(CN)_(4)]^(2-)` is a high spin complex.
`[NiCl_(4)]^(2-)` is tetrahedral while `[Ni(CN)_(4)]^(2-)` is SQUARE planar.
`[NiCl_(4)]^(2-)` involves `SP^(3)` hybridisation and `[NiCN_(4)]^(2-)` involves `dsp^(2)` hybridisation.
