Solid-State Synthesis and Characterization of a Copper(II) Complex with o-Vanillin

Abstract

The complex, [Cu(C₈H₇O₃)₂H₂O], has been synthesized by the solid-state reaction of copper acetate and o-vanillin (C₈H₈O₃) ligand. The complex was characterized by X-ray powder diffraction, elemental analysis, FTIR spectra and TGDTG. The elemental analyses indicate 1:2 (metal:ligand) stoichiometry for the complex. The spectral studies show that the ligand acts as a bidentate ligand with the phenolic-CO and carbonyl group as coordinating donor sites and the H₂O was coordinated with Cu(II) ion. The suggested coordination number is five in this complex.
