The reaction of [(Hyp)2Ge9]2– (Hyp = Si(SiMe3)3) with ClSiMe2-C6H4-SiMe2Cl gives [K(THF)][(Hyp)2Ge9-SiMe2-C6H4-SiMe2-Ge9(Hyp)2K] K1 in 45% yield in the form of orange-red crystals. 1 is thereby the first compound where two Ge9(Hyp)2 clusters are bound together via a bridging ligand. 1 is stable in solution but cannot be transferred intact into the gas phase via electrospray ionization indicating a higher reactivity with respect to other metalloid Ge9R3 clusters. The arrangement of the nine germanium atoms within the two Ge9 units in 1 is unique for metalloid Ge9R3 clusters. Quantum chemical calculations further reveal an electronic interaction of the two Ge9 units in 1 via the bridging phenylene group.

{[硅(森达33 ] 2的Ge 9 -SiMe 2 - (C 6 H ^ 4)-SiMe 2 -Ge 9 [硅(森达33 ] 2 ķ} - :通过有机链接剂类金属簇的连接

[脯氨酸(Hyp)的反应2的Ge 9 ] 2-脯氨酸(Hyp = SI(森达33)与ClSiMe 2 -C 6 H ^ 4 -SiMe 2氯给出[K(THF)] [脯氨酸(Hyp)29 -森达2 -C 6 H ^ 4 -SiMe 2 -Ge 9脯氨酸(Hyp)2 K] K1,收率45%橙红色晶体的形式。因此,图1是第一化合物,其中两个Ge 9(Hyp)2簇通过桥连配体结合在一起。1个在溶液中是稳定的,但不能通过电喷雾电离完整地转移到气相中,这表明它相对于其他准金属Ge 9 R 3团簇具有更高的反应性。两个戈内的九个锗原子的排列91为金属锗独特9 - [R 3簇。量子化学计算进一步揭示了1中两个Ge 9单元通过桥联亚苯基的电子相互作用。
