摘　　要：用电导滴定法研究了乙醇-水溶液中稀土与1’-苯基-3’-甲基-5’-氧代吡唑-4’-基-甲酰甲酸及1,10-二氮杂菲的配合反应。合成了固态配合物。经化学分析与元素分析确定了配合物的化学组成为Ln_2L_3P_2·nH_2O,通过红外光谱、紫外光谱、~1H NMR谱、差热分析、溶解度等方法对配合物进行了表征,确定Ln_2L_3P_2·nH_2O为双核结构(L为四齿配体,P为二齿配体)。The coordination reactions of rare earth elements with 1' -phenyl-3' -methyl-5' -oxopyra-zole-4'-formylmethanoic acid and 1, 10-phenanthroline have been studied by electric conductance titration. Thirteen new solid ternary coordination compounds were synthesized and characterized by elemental analysis, infrared, ultraviolet, proton magnetic resonance and thermogravimetric analysis. Their composition were proved to be RE2L3P2 nH2O, where RE are rare earth elements except Sc, Ce,Pm, Lu: L is 1' -phenyl-3' -methyl-5' -oxopyrazole- 4' -formylmethanoic acid, P is 1, 10-phenanthroline, n=4~6. 0n the basis of all above investigation, it can be concluded that these complexes belong to binuclear structure.
