Emphasis has been put on determining the conditions for the synthesis of both deprotonated and non-deprotonated NiII complexes. They were characterized by analyses, conductivity measurements, thermogravimetry, magnetic susceptibility and spectroscopic methods like i.r. and far-i.r., diffuse reflectance u.v. vis, and e.s.r. Monomeric square planar and distorted octahedral structures were found for the deprotonated complexes in the solid state while the non-deprotonated NiII complexes appeared to be pseudo-tetrahedral polymers. The doubly deprotonated L2-ion exhibits a bidentate N(amide), N(amide)-coordination, while the neutral LH2 molecule behaves as a N(amino), N(amino)-bidentate ligand forming polymeric structures. Vibrational analysis of the complexes was carried out, using hydrogen and metal isotopic substitution.
