SYNTHESIS, CHARACTERIAL THE COMPLEXES OF NANO Sm(III), Eu(III) WITH MIXTURE LIGAND L - GLUTAMIC ACID AND IMIDAZOLE

Abstract

   The complexes Ln(Glu)3ImCl3.3H2O (Ln: Sm, Eu; Glu: L-Glutamic acid; Im:Imidazole) have been synthesized and characterized by the elemental analysis methodmolar conductance, IR spectra, thermal analysis and transmission electronmicroscopy (TEM). IR spectra indicated that the rare earth ions are coodinated byboth the oxygen atom from the COO- group and the nitrogen atom from the NH2group from L-glutamic acid and coodinated with the 3-nitrogen atom for imidazole.The TEM image indicated that the complexes were regular shaped and the length wasabout ~60nm.
