The disproportionation reaction of the subvalent metastable halide SnBr proved to be a powerful synthetic method for the synthesis of metalloid cluster compounds of tin. Hence, the neutral metalloid cluster compound Sn(10)Si(SiMe(3))(3) (3) was synthesized from the reaction of SnBr with LiSi(SiMe(3))(3). In the course of the reaction anionic clusters might also be present, and we now present the first anionic cluster compound {Sn(8)ESi(SiMe(3))(3)}(-) (E = Si, Sn), where one position in the cluster core is occupied by a silicon or a tin atom, giving further insight into structural variations of E(9) cages in metalloid group 14 cluster compounds.
亚稳态卤化物 SnBr 的歧化反应被证明是合成锡的类金属簇合物的有效方法。因此，中性类金属簇合物 Sn(10)Si(SiMe(3))(3)（3）是通过 SnBr 与 LiSi(SiMe(3))(3)反应合成的。在反应过程中可能也存在阴离子簇，我们现在提出了第一个阴离子簇化合物{Sn(8)ESi(SiMe(3))(3)}(-)（E = Si，Sn），其中簇核的一个位置被一个硅或锡原子占据，进一步深入了解了 14 族类金属簇合物中 E(9)笼的结构变化。
