Synthesis and Characterization of Some Transition Metal Complexes of N-(2-Hydroxy-1-naphthylidene) Amino Acids

Abstract

A new series of Co(II), Ni(II), Cu(II) and Zn(II) complexes with Schiff bases derived from the condensation of 2-hydroxy-1-naphthaldehyde with glycine, L-valine and L-phenyl-alanine has been synthesized. The complexes were characterized on the basis of elemental analyses, ¹H NMR, IR, conductivity, magnetic susceptibility measurements and electronic spectral data. The metal complexes were synthesized with in situ prepared N-(2-hydroxy-1-naphthalidene)amino acids. Spectral data indicate that the ligands function as dibasic terdentate ligands with O, N and O donor atoms.
