Ni2+ schiff base complexes are paramagnetic but it doesn't show signals in EPR Spectra both in room & LNT temp?

Then by which characterization it can be conformed.

By which approach did you verify that they are paramagnetic in the first place? Ni2+ standalone is paramagnetic, but if you have a square planar complex of it, it will be diamagnetic.

A macroscopic verifier would be a Quincke susceptibility measurement:

Why doesn't chromium 2+ ion use all its d-orbitals to receive lone pairs from six waters in [Cr(H20)6)]3+?
