Synthesis and Spectroscopic Studies of Transition Metal Complexes of Mononuclear Schiff Base Derived from 4-Methoxybenzaldehyde and Glycine

Abstract

A new bidentate nitrogen/oxygen containing Schiff base ligand (L) where L = 4- methoxybenzaldehyde-glycine and their transition metal complexes have been synthesized and well characterized by elemental analysis, infrared spectroscopy, electrons spray ionization mass spectrum, molar conductivity measurement, magnetic moments at the room temperature, electronic spectrum, ¹H NMR, ¹³C NMR spectrum and physico-chemical studies. On the basis above results confirmed that the synthesized ligand acts as bidentate. The conductivity measurement data in DMSO/DMF solution indicated that all the cholro complexes are essentially non-electrolyte in nature. Thus, a hexa coordinated environment was generated around the metal ions have been proposed by the ligand and all the complexes have been screened for biological activity on several pathogenic fungi and bacteria and were found to possess appreciable fungicidal and bactericidal properties.
