Synthesis and Spectroscopic methods on the complexation ofCoII, NiII and CuII

Abstract

The Ligand was synthesized by condensation of Indol 3-hydroxy aldehyde, Glycine and Hydrazine hydrate. The reaction of the ligand with ions (CoII, NiII and CuII ions) yielded complexes, these compounds were characterized by physical and spectroscopic techniques. The conductivity showed a non-electrolytic nature for these compounds. The elemental analysis indicated the ligand to metal ratio as 1:1 with general molecular formula M(L)(H2O)nCl2 (L=ligand; M=metal ions. IR data showed the ligand coordinated to the metal ion via azomethine nitrogen and amine of hydrazide in addition to the amine of indol ring with CuΙΙ. The spectral and magnetic studies of the complexes showed that octahedral geometry for CoΙΙ and NiΙΙ while for CuΙΙ distorted octahedral geometry. The particle size and strain of these compounds have been discussed using X-ray diffraction. The antioxidant study for ligand proved to be a good antioxidant. The compounds have been evaluated for their antimicrobial activity against various organisms.
