A series of ternary lanthanide complexes Ln(C6H5CHOHCOO)3(phen)(H2O)(Ln=La,Ce,Pr,Nd,Sm,Eu)were synthesized with α-hydroxyl-phenyl-acetic acid and 1,10-phenanthroline(phen)as ligands.The structure and property of comp...A series of ternary lanthanide complexes Ln(C6H5CHOHCOO)3(phen)(H2O)(Ln=La,Ce,Pr,Nd,Sm,Eu)were synthesized with α-hydroxyl-phenyl-acetic acid and 1,10-phenanthroline(phen)as ligands.The structure and property 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 determined by thermogravimetry was indicated that the degree of co-ordinate ability of ligand was:α-hydroxyl-phenyl-acetate ion > 1,10-phenanthroline(phen).展开更多

In the crystal lattice, the molecules create a network structure through hydrogen bonds. The second order optical non- linearity was performed by quantum chemical method, showing the title compound has higher molecular hyper polarizability value (?= 24.66×10-30 esu).展开更多
