摘要： 用萃取法合成了15种1,2-双(1'-苯基-3'-甲基-5'-氧代吡唑-4'-基)-1,2苯二酮(BPMOPP,简作H2L)稀土配合物。元素分析确定其化学组成为RE2L3·nH2O.通过电子光谱、红外光谱、核磁共振谱、热谱、摩尔电导等进行了表征,并讨论了配合物的性质。

Abstract: Anew ligand 1, 2-bis (1'-phenyl-3'-methyl-5'-oxopyrazol-4'-yl)-1, 2-phthaldione (H2L) and its rare earth complexes were prepared by the reaction of H2L with relative metal nitrate in aqueous solution. The binuclear structures of the complexes are proposed according to the elementary analysis results, molar conductance, IRand 1H NMRspectra.

Key words: Rare earth elements, Complexes, 1,2-Bis( 1'-phenyl-3'-methyl-5'-oxopyrazo-4'-yl)-1,2-phthaldione
