Synthesis and Properties of Ternary Europium Complexes with Phthalate Acid and Phenanthroline

Five ternary complexes of Eu(Ⅲ) were synthesized with o(m,p)-phthalate as the first ligand,and 1,10-phenanthroline(phen) as the second ligand.They were characterized by elemental analysis,IR and TG-DTG methods.In these complexes,the metal ions were bonded to the oxygen atoms of carboxylate and the nitrogen atoms of phen.The TG-DTG analysis showed that these complexes were thermally stable.The excitation and luminescence spectra were carried out at room temperature.
