Synthesis and Spectral Studies of Cr(III), Mn(II), Co(II), Ni(II), Cu(II) and Cd(II) Complexes with New Bidentate (N,O) Schiff Base Ligand bearing an Oxime functional group

Abstract

The new Schiff base ligand has been prepared viacondensation reaction of o-aminoacetophenonoximeand3-Ethoxysalicylaldehyde. This ligand has been characterized by different techniques such as, (IR, U.V-Vis) spectroscopy, (1H, 13C) NMR spectra, GC-Mass spectrum and micro-elemental analysis. Its Cr(III), Mn(II), Co(II), Ni(II) and Cu(II) complexes prepared and characterized by (IR, U.V-Vis) spectroscopy, magnetic susceptibility, conductivity measurements and atomic absorption. The ligand acts as monobasic bidentate with (N,O) set donar and coordinates through phenolic group oxygen atom and imine azomethine nitrogen atom. Octahedral geometry structure proposed to Cr(III), Mn(II), Cu(II) and Cd(II) show, while tetrahedral and square planar structures were proposed to complexes of Co(II) and Ni(II), respectively.
