Polyhedral main group element clusters of tetrel elements are discussed as suitable building units to form atom-precise nano-structures. Herein we report the oxidative coupling of two [Ge9Si(TMS)3}2]2− clusters (TMS = trimethylsilyl) resulting in the dimeric cluster [Ge9Si(TMS)3}2]22−. The dimer is structurally characterized as the [NHCiPrCu]+ adduct NHCiPrCu[Ge9Si(TMS)3}2]}2 [NHCiPr = 1,3-di(
Tetrel 元素的多面体主族元素簇被讨论为合适的构建单元以形成原子精确的纳米结构。在这里,我们报告了两个 [Ge 9 Si(TMS) 3 } 2 ] 2-簇 (TMS = 三甲基甲
硅烷基)的氧化偶联,产生了二聚簇 [Ge 9 Si(TMS) 3 } 2 ] 2 2-。二聚体的结构特征为 [NHC iPr Cu] +加合物 NHC iPr Cu[Ge 9 Si(TMS) 3 } 2 ]} 2 [NHC iPr= 1,3-二(异丙基)
咪唑啉]。两个分子 [Ge 9 Si(TMS) 3 } 2 ] 2-阴离子的键合在形成外Ge-Ge 键的情况下发生在 Cy 2 BCl (Cy = 环己基) 的存在下,并由微量氧介导如副产物 Cy 2 B-O-BCy 2的分离所示。
