1，8－双－（1＇－苯基－3＇－甲基－5＇－氧代吡唑－4＇－基）－3，6－二氧杂辛二酮－［1，8］稀土配合物的合成与表征

Synthesis and Characterization of Complexes 1, 8 Bis (1'-pheny 1-3'-methy1-5'-Oxopyrazo-4'-yl) -3, 6-Dioza-1. 8-Octanedione with Rare Earth Elements

在乙醇溶液中合成了７种１，８—双—（１＇苯基—３＇—甲基—５＇—氧代吡唑—４＇—基）—３，６—二氧杂辛二酮—［１，８］，（简作Ｈ２Ｌ）稀土配合物。元素分析确定其组成为ＲＥ２Ｌ３·ｎＨ２Ｏ。通过电子光谱、红外光谱、核磁共振谱、热谱、荧光光谱、摩尔电导等进行了表征。

Seven solids complexes novel ligand 1, 8 (1' phenyl 3' methyl 5' oxopyrazo 4' yl ) 3, 6 dioxa 1, 8 octanedione (H2L) with rare earth elements have been prepared by reacting H2L with rare earth nitrates in ethyl alcohol solution. The results of elemental analysis shown that the composition of complexes were RE3L3·nH2O (RE= La, Nd, Sm, Eu. Tb, Dy, Sc) and the complexes have been characterized by thermoanalysis, molar conductivity, IR, UV, 1H NMR and fluorescence spectra measurements.
