摘要：
For the synthesis of metalloid cluster compounds of tin applying the disproportionation reaction of subvalent metastable Sn(I) halides, Si(SiMe3)(3) proved to be the ligand with the highest synthetic potential. However, degradation of the Si(SiMe3)(3) ligand can also lead to cluster enlargement where additional silicon atoms are incorporated into the cluster core. Here we describe the structure and bonding of the novel anionic cluster compound {Sn10Si(SiMe3)(2)[Si(SiMe3)(3)](4)}(2-) 5, where such a degradation has taken place. Additionally, requirements for the formation of 5 are discussed.
