Copper(II) and Zinc(II) Complexes of Schiff Bases Derived from Amino Acids andO-Vanillin

摘要

Some new Cu(II) and Zn(II) complexes of Schiff bases derived fromo-vanillin and glycine, DL-alanine, DL-valine, DL-methionine, L-leucine, and L-phenylalanine have been synthesized and characterized by elemental analyses, molar electrical conductivity, electronic and infrared spectra, and thermogravimetric analyses. The results suggested that the Schiff bases are bivalent anions with tridentate ONO donors derived from the carboxylate oxygen, imino nitrogen, and phenolic oxygen. These complexes are nonelectrolytes.
