The structures of diiodosamarium(II) complexes with amide compounds have been investigated basing on single crystal X-ray structural analyses. The reaction of [SmI2(thf)2] with 2 equivalents of tetramethylurea (TMU) gave [SmI2(thf)2(tmu)2] (1). The three different kinds of ligands in 1 attach to the samarium atom in a trans orientation. [SmI2(thf)2] reacted with 4 equivalents of 1,3-dimethyl-2-imidazolidione
已经基于单晶 X 射线结构分析研究了二碘钐 (II) 与酰胺化合物的配合物的结构。[SmI2(thf)2]与2当量的四甲基脲(TMU)反应得到[SmI2(thf)2(tmu)2](1)。1 中的三种不同类型的配体以反式取向连接到钐原子。[SmI2(thf)2]与4当量的1,3-二甲基-2-咪唑啉酮(DMI)反应得到[SmI2(dmi)4](2),形成典型的六配位八面体结构。含有四个 N,N-二甲基乙酰胺 (DMA) 配体 [SmI2(dma)4] (3) 的 Diiodosamarium 复合物是通过用 4 当量的 DMA 处理 [SmI2(thf)2] 来制备的。[SmI2(thf)2] 与 6 当量的 1,3-二甲基-3,4,5,6-四氢-2-(1H)-嘧啶酮(二甲基丙烯脲 (DMPU))反应得到 [Sm(dmpu)6 ]I2 (4) 定量。该复合物具有独特的配位方式,其中六个 DMPU
