title: Tetrasilane-bridged bicyclo[4.1.0]heptasil-1(6)-ene.
abstract: Tetrasilane-bridged bicyclo[4.1.0]heptasil-1(6)-ene 1 was synthesized by the reduction of 1,1,2,2-tetrachlorocyclohexasilane 2 in 12% yield as red-orange crystals. The structure and properties of 1 were studied by spectroscopy, X-ray crystallography, and theoretical calculations. The linkage of the cyclotrisilene moiety with two tetrasilane chains with tert-butyl groups remarkably affects its structure and (29)Si NMR spectrum.
