Q. Among the following the species that is both tetrahedral and diamagnetic is

KVPYKVPY 2012Coordination Compounds

Solution:

In $Ni(CO)_4, Ni$, is in $0$ oxidation number thus,
its electronic configuration is $3d^8 4s^2$.

As $CO$ is a strong field ligand and pairing of electrons occurs thus its configuration becomes$3d^{10} 4s^0$.

As $Ni(CO)_4$ has $sp^3$ -hybridisation, so its geometry will be tetrahedral.
Also, all the electrons are paired, so it is diamagnetic in nature.
