Tetrasilane-Bridged Bicyclo[4.1.0]heptasil-1(6)-ene Akihiro Tsurusaki Jun Kamiyama Soichiro Kyushin 10.1021/ja507279z.s001 https://acs.figshare.com/articles/journal_contribution/Tetrasilane_Bridged_Bicyclo_4_1_0_heptasil_1_6_ene/2254354 Tetrasilane-bridged bicyclo­[4.1.0]­heptasil-1­(6)-ene <b>1</b> was synthesized by the reduction of 1,1,2,2-tetrachlorocyclohexasilane <b>2</b> in 12% yield as red-orange crystals. The structure and properties of <b>1</b> were studied by spectroscopy, X-ray crystallography, and theoretical calculations. The linkage of the cyclotrisilene moiety with two tetrasilane chains with <i>tert</i>-butyl groups remarkably affects its structure and <sup>29</sup>Si NMR spectrum. 2014-09-17 00:00:00 cyclotrisilene moiety calculation bicyclo crystallography 29 Si NMR spectrum tetrasilane chains linkage tetrachlorocyclohexasilane Bicyclo crystal spectroscopy
