Synthesis and characterization of some monofunctional bidentate Schiff bases derived from cinnamaldehyde and s-triazoles, and their Co(II),. Ni(II), Cu (II) and Zn(II) complexes

Abstract

A new series of complexes of Co(II), Ni(II), Cu(II) and Zn (II) with Schiff bases derived from the condensation of cinnamaldehyde with 4-amino-5mercapto-s-triazole and 4-amino-5-mercapto-3-methyl-s-triazoIe have been synthesized. The complexes are characterized by elemental analyses, 'H NMR, IR, electronic spectra and magnetic susceptibility measurements. The spectroscopic studies reveal that Schiff base acts as bidentate ligand with N, S donor set. Thermal studies of the complexes are also reported. Keywords. Metal complexes; Schiff base complexes; bidentate ligands.
