闭式－氢硼酸二茂铁甲酰丙酮缩异菸肼稀土配合物 FERROCENOYLACETONE ISONICOTINOYL HYDRAZONE COMPLEXES OF RARE EARTH CLOSO-HYDROBORATES 胡培植 1 first-author 季立才 1 张奇志 1 张伦 1 武汉大学化学系 武汉大学化学系 Department of Chemistry,Wuhan University Department of Chemistry,Wuhan University 将二茂铁甲酰丙酮与异菸肼缩合，生成金属有机多齿新配体，该配体（ＦＣＲ）与闭式－十二氢十二硼酸稀土化合物反应，得到分子式为［Ｌｎ（ＦｃＲ）２］２（Ｂ１２Ｈ１２）３·ＸＨ２Ｏ（Ｌｎ＝Ｌａ，Ｎｄ，Ｅｕ，Ｇｄ，Ｄｙ，Ｈｏ，Ｅｒ，ＴｍａｎｄＬｕ）的９个配位化合物，经元素分析、红外光谱、紫外光谱对其组成、结构进行了表征，通过ＴＧ－ＤＴＡ研究了它们的热行为． A novel organometallic ligand, ferrocenoylacetone isonicotinoyl hydrazone（FcR）,was obtained from the condensation of ferrocenoylacetone with isonicotinyl hydrazineand nine new FcR complexes of lanthanide closo-dodecahydrododecaborates were synthesizedby the reaction of FcR and lanthanide hydroborates. The complexes which have the generalformula [Ln （FcR ）2]2 （B12H12）3· xH2O （Ln= La, Nd, Eu, Gd, Dy, Ho, Er, Tm and Lu ） werecharacterized by elemental analysis,IR and UV spectra. The thermal behaviour of the complexes was investigated by TG-DTA. 稀土配合物 金属有机配体 闭式－氢硼酸 合成与表征 rare earth complex organometallic ligand closo-hydroborate synthesis and characterization O614.33 国家自然科学基金(61672102) 1995-04-01 2021-04-01 4
