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。
In this paper, La ~ (3+) and 1,5-bis (1’-phenyl-3’-methyl-5’-oxopyrazol- , 5] (BPMPPD) and triphenylphosphine oxide (TPPO). The composition of the complex was determined to be La_2 (BPMPPD) _3 (TPPO) _2 · 8H_2O by elemental analysis, chemical analysis and conductivity analysis. The UV, IR, 1H-NMR spectra and thermal stability of the complexes were studied. It is proved that the complex is a dinuclear structure and BPMPPD is a tetradentate ligand.
