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 29Si NMR spectrum.
