As we have learned
Magnetic Moments (spin only) -
where n= number of unpaired electron.
- wherein
Number of unpaired and corresponding magnetic moments
The electronic configuration of Ni in
and
are as following
CO and are strong ligands so they induces pairing of electrons so their complexes are diamagnetic while
is a weak ligand so it does not induce the pairing of electrons so its complex is paramagnetic.
