| Abstract: The new multidentatc complexes LnGly(BipyO2)2Cl3,·H2O and LnGly(BipyO2)2(NO3)3·H2O(Ln=La, Ce, Pr, Nd, Sm and Eu; Gly=glycine and BipyO2=2,2 ' -bipyridine-N,N ' -dioxide)have been synthesized using methanol as reaction medium. The IR spectra show that the Gly in the complexes keeps the inner salt structure and is coordinated to the metal ion as an unidentate ligand. The BipyO2 molecules are poordinatcd to the mcial ion through oxygen at oms. When irradiated with ultraviolet lamp(254nm)the europium complexes exbibit intense red fluorescence. The molar conductance data measured in methanol solution indicate that all of the complexes are 1:1 electrolyte, as suggests that one of the three anions in each complex molecule is not coordinated to the metal ion. The results of DSC-TGA show that the water molecules in the complexes are crystal water and the dehydrated complexes are stable below 200℃. |
