Spectroscopic Elucidation of some Complexes of Vanillin Semicarbazone

3-Phenyl-4-methoxybenzaldehyde undergoes condensation with semicarbazide hydrochloride to form a Schiff base i.e. 3-phenyl-4-methoxybenzaldehyde semicarbazone (abbreviated as MBS). It undergoes complexation with Vanadium(II), Manganese(II), and Copper(II). The comparison of FTIR-spectra of complexes with that of free ligand helps ascertain the coordination points of ligand through the nitrogen of -CH=N- group and oxygen of group. The axial ligands have been varied by chloride, acetate and nitrate ions. The UVNisible and ESR spectra of complexes predicts their tetragonally distorted octahedral (D-4h) symmetry. The tetragonal distortion parameter (D-t) is observed maximum for chloride while it is minimum for nitrate along z-axis. Both vanillin and semicarbazide are established biologically active compounds and hence their biological activities may be enhanced by their complexation and than a versatile field may be developed for further exploration.
