摘要： 将[Et4]2B12H12与丙二腈反应,生成化合物Et4NB12H11NCCH2CN,水解后得[Et4NB12H11NHCOCH2CONH2]-·[Et4NBN]-,该衍生物与稀土氯化物(LnCl3)及2,2＇-联吡啶-N,N＇-二氧化物(bipyO2)反应,合成了几种新型的混配稀土配合物Ln(bipyO2)4(Et4NBN)3(Ln=La,Nd,Sm,Gd,Dy,Ho,Er).元素分析确定了它们的组成,通过IR、UV、1HNMR、ESR、摩尔电导测定及TG-DTA等对其性质进行了研究。

Abstract: Mono-substituted amide derivative of [Et4N]2B12H12, [Et4N]2B12H11NHCOCH2CONH2·([Et4N]2BN), was obtained from acid-catalyzed reaction between [Et4N]2B12H12and malononjtrile, followed by hydrolysis. The derivative reacts with lanthanide chlorides and 2, 2'-bipyridine-N,N'-dioxide (bipyO2) to produce 7 novel mixed-ligand rare earth (Ⅲ) complexes with the formula Ln(bipyO2)4(Et4NBN)3, where Ln = La, Nd, Sm, Gd, Dy, Ho and Er. These complexes were characterized by elemental analysis, IR, UV, 1HNMR, ESRand molar conductivities. The thermal properties of the ligands and the complexes were investigated by TG-DTA.
