Abstract
GLYCINE (Gly) complexes play an important role in human life. Zn(II), Cu(II), Ni(II), Fe(III), Mn(II), and Cr(III) complexes were synthesized with glycine (Gly). These complexes were characterized by infrared spectroscopy (FT-IR). Based on the stoichiometric data, Gly form a chelate complex in a bidentate fashion at a 1:3 ratio with the trivalent metal ions [Cr(III), Fe(III)] and a 1:2 ratio with the divalent ones [Mn(II), Ni(II), Cu(II) and Zn(II)]. Metal oxides were derived from each of the Gly complexes using thermal decomposition at 800°C. FT-IR analysis of the resulting solids revealed their formation in pure form.
