X-Ray Diffraction Studies of Iron(II), Nickel(II) and Copper(II) Complexes of o-Vanillin-L-Histidine

Abstract

o-Vanillin-L-histidine was synthesized by refluxing o-vanillin with L-histidine. This o-vanillin-L-histidine (o-VALH) was used to synthesize iron(II), nickel(II) and copper(II) complexes having metal to ligand stoichiometry 1:1. The ligand and metal complexes were characterized by elemental analysis, molar conductivity, electronic absorption and IR absorption spectra. The magnetic nature of the complexes was established using Gouy's balance method. The XRD data was used to index the compound for orthorhombic system.
