NH groups, respectively. The values of magnetic for all Ni2+ complexes suggest the existence of octahedral geometry around the NiII ion in the monomeric or in the dimeric forms. In all cases the ligandsform five-member rings around the NiII ions. Also, the results of electronic spectra suggest an octahedral geometry around the NiII ion. Moreover, the results of thermal studies indicate the mechanism
