Synthesis and Characterization of Bio Active Transition Metal Complexes of Cu(II) Co(II) and Ni(II) using Natural Sources

Abstract

Cardanol a naturally occurring C15 unsaturated aliphatic chain substituted phenol derived from cashew nut shell liquid (CNSL) was used for the preparation of Schiff base ligand using Glutamine. Di-α-formylmethoxybis(3pentadecenylphenyl)methane (DFMPM) is prepared from cardanol using standard methods. The ligand formed Schiff base complexes with Cu(II), Co(II) and Ni(II) ions. The ligand and complexes were characterized by UV-visible, IR, and the elemental analysis, melting point, metal ion intake, SEM, XRD antibacterial and antifungal activity were studied. The result indicate that the complexes of Cu(II), Co(II) and Ni(II) 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.
