Of the following complex ions, which is diamagnetic in natures?

A

`[CoF_(6)]^(3-)`

B

`[NiCl_(4)]^(2-)`

C

`[Ni(CN)_(4)]^(2-)`

D

`[CuCl_(2)]^(2-)`

Text Solution

Verified by Experts

The correct Answer is:
C
Ni has `dsp^(2)` hybridisation where `CN^((-))` is a strong field ligand.

Since, all the electrons are paired, it is diamagnetic.
