该文以Α－呋喃甲酸(C5O3H4 )和邻菲罗啉(C12H8N2 )为配体,在乙醇溶剂中与硝酸镧反应,合成了与稀土离子LA(Ⅲ)的三元混配配合物.经元素分析确定其配合物的组成为LA(C5O3H3 )3 ·C12H8N2·H2O,同时还通过IR、1H NMR、UV、TG－DTA等谱学的测试与分析,表征了配合物的组成结构和性质.IR、1H NMR和UV 谱的分析结果表明配体羧酸是以脱质子的酸根形式与中心稀土离子LA(Ⅲ)配位的,而邻菲罗啉配体上的N原子则采用了双齿螯合配位形式.TG－DTA的数据分析表明,化合物在常温下是稳定的.随着温度的上升,配合物先后经历了一个脱水、有机配体的氧化分解、直至生成稳定的LA2O3 的过程.其定量分析结果与配合物的组成是一致的“,”The title ternary complex La(C 5O 3H 3) 3·C 12 H 8N 2·H 2O was synthesized by reaction of lanthanum nitrate with α furoic acid (C 5O 3H 4) and 1,10 phenanthroline (C 12 H 8N 2) as ligand in the alcohol solvent.The composition of the complex was determined by element analysis.Its structure and properties were characterized by IR, 1H NMR,UV and TG DTA.IR, 1H NMR,UV spectra showed that the ligand α furoic acid coordinate to the center ion La(Ⅲ) with the deprotonized form,and 1,10 10phenanthroline with the bidentate form using its two N atoms.The TG DTA analysis exhibited that the complex is stable in the range of room temperature and undergo the disassociation of water and oxygenized decomposition of the organic ligands in order with the rising of temperature,and the final oxide obtained is La 2O 3.The quantitative analysis of TG DTA was coincided with the structural composition of the title complex.
