A Convenient Method to Synthesis and Characterization of Ni(II) and Zn(II) Schiff Base Complexes

Abstract

We have synthesized the schiff base and two metal-organic coordination compounds: [Ni(C₂₈H₁₈N₂O₂)] complex 1 and [Zn(C₂₈H₁₈N₂O₂)] complex 2, using liquid-assisted mechanochemical grinding (LAG). The compounds were characterized by infrared, X-ray Powder Diffraction, Energy dispersive x-ray, Differential scanning calorimetry and Thermogravimetric analysis, in all the complexes formed, the ligand coordinated with the metal ion through the two nitrogen atomsof the azomethine group (-N=C-) and two phenolic oxygen atoms of the schiff base to complete square planar geometry. The melting point, colour and X-ray diffraction patterns of the complexes were different from that of the schiff base ligand suggests formation of coordination compounds.
