Question

The geometry and magnetic behaviour of the complex [Ni(CO)4][Ni(CO)_4] are

A

Square planar geometry and paramagnetic

B

Tetrahedral geometry and diamagnetic

C

Square planar geometry and diamagnetic

D

Tetrahedral geometry and paramagnetic

Step-by-Step Solution

For Ni(28):[Ar]3d84s2Ni(28) : [Ar]3d^8 4s^2. Since CO is a strong field ligand, it causes pairing of electrons, resulting in sp3sp^3 hybridisation. Thus, the complex is tetrahedral and diamagnetic.
