摘要：

Reaction of KH with PhMe2SiOH in toluene, followed by recrystallization from benzene, gives [(C6H6)KOSiMe2Ph]4, characterized by elemental analysis, H-1 and Si-29 NMR and X-ray diffraction. The molecule is a cubane tetramer of rigorous S4 symmetry, in which the KO3 coordination environment is supplemented by eta-6-binding of one benzene to each potassium. Crystal data (-169-degrees-C): a = 12.972(2), b = 18.006(2) angstrom, with Z = 8 in space group I4BAR.
