ABSTRACT
Starting from Sn(I) halides, available via a preparative co-condensation technique, we have established a fruitful route to metalloid tin clusters in recent years. Applying a Sn(I)Cl solution, we were able to obtain the open anionic metalloid tin cluster [Sn10[Si(SiMe3)3]4]Citation2− 1 in high yield. In 1 the tin atoms are incompletely shielded by the ligand shell so that subsequent reactions seem possible. Hence, a first step toward a chemistry applying metalloid tin clusters was done and we describe first investigations concerning the formation of 1 and its reactivity.
