    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 N3- 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.
