The carborane homologous, icosahedral o ‐disilaborane 1 is formed together with other products upon reaction of B 10 H 14 with bis(dimethylamino)(methyl)silane in boiling benzene. The SiSi distance of 2.308(2) Å would suggest that the Si 2 ‐unit in 1 may formally be regarded as a doubly bridged disilyne MeSiSiMe. 1 is air‐stable and inert toward acids; in KOH solution, however, it decomposes within minutes.
