Spectra. Its Ni(II) complex was synthesized and characterized by analytical studies, molar conductivity, magnetic susceptibility, IR and UV-Vis. Spectra. The metal to ligand ratio is 1:1 and the metal complex is a non-electrolyte. Based on the spectral data and magnetic susceptibility measurement, dibasic ONNO donor behavior of the ligand and octahedral geometry for the brick-red colored complex have been concluded.
