Two new mononuclear Ni(II) complexes with reduced ONNO type Schiff base

N,N′-bis(salicylidene)-1,3-propanediamine (LH₂) and N,N′-bis(salicylidene)-2,2′-dimethyl-1,3-propanediamine (DMLH₂) were reduced to phenolic amines by using NaBH₄. Mononuclear complexes were obtained with Ni (II) in a N₃O₆ coordination sphere with these amines and N_3– ions, in DMF media. It was established with the XRD studies that the coordination spheres were distorted octahedral and the complex obtained with LH₂ formed dimeric structures via phenolic OH bonds. The other complex was seen to have monomeric structure. The complexes were characterized by X-ray diffraction, elemental analysis, termogravimetry, IR spectroscopy and simple magnetic susceptibility (Gouy method). In addition, cyclic voltammetric studies have been performed.
