摘　　要：本文在乙醇介质中合成了La^(3+)与1,5-双(1′苯基-3′-甲基-5′-氧代吡唑-4′-基)戊二酮-[1,5](BPMPPD)和三苯基氧化膦(TPPO)的三元配合物。通过元素分析、化学分析及电导分析确定了配合物的组成为La_2(BPMPPD)_3(TPPO)_2·8H_2O。研究了配合物的紫外、红外、核磁共振光谱及热稳定性。证明配合物为双核结构,BPMPPD为四齿配体。A mixed-ligand complex has been prepared by the reaction of lanthanum chloride with 1, 5-bis (l′-phenyl-3′-methyl-5′-pymzolone-4′-)-1, 5-pentanedione (BPMPPD) and triphenylphosphine oxide (TPPO). Elemental analysis shows that its formula is La_2 (BPMPPD)_3 (TPPO)_2 · 8H_2O. And its properties have also been studied by means of conductivity, IR, UV, HNMR and DTA TGtechniques. On the basis of the above investigations it can be thought that the complex is of a binuclear structure and BPMPPD is a tetradendete ligand.
