Synthesis and Characterization of Bio active Transition Metal Complexes of Zr(IV) and Th(IV) using natural sources

Abstract

Cardanol, a naturally occurring aliphatic side chain substituted phenol derived from cashew nut shell liquid (CNSL) was used for the preparation of Schiff base ligand using Glutamine. The ligand formed Schiff base complexes with Zr(IV) and Th(IV)  ions. The ligand and complexes were characterized by UV-visible, IR, and the elemental analysis, melting point, metal ion intake, SEM, XRD antibacterial,antifungal,anti-inflamatory and DNA clevage were studied. The result indicate that the complexes of Zr(IV) nd Th(IV)) are hexaco-ordinated and have moderate antibacterial and antifungal activity. The metal ion intake indicated the ligand can be used for the removal of these metals from water. The SEM and XRD studies revealed the nano crystalline nature of the complexes.
