A series of ternary lanthanide complexes Ln(C6H5CHOHCOO)3(phen) (H2O) (Ln= La, Ce, Pr, Nd,Sin, Eu) were synthesized with α-hydroxyl-phenyl-acetic acid and 1, 10-phenanthroline (phen) as ligands. The structure and of complexes were characterized by elemental analysis, IR, 1H-NMR, UV and TGA, and the co-ordinate mode of both ligands was discussed. It was shown that the co-ordinate mode of 1, 10-phenanthroline was chelated,while α-hydroxyl-phenyl-acetate ion was monodentate or bridging. The mechanism of thermal by thermogravimetry was indicated that the degree of co-ordinate ability of ligand was: α-hydroxyl-phenyl-acetate ion＞1, 10-phenanthroline (phen).
