9,9-Dimethyl-9-silafluorene

The title compound, C(14)H(14)Si, crystallizes with two almost identical mol­ecules (r.m.s. deviation = 0.080 Å for all non-H atoms) in the asymmetric unit. All atoms of the silafluorene moiety lie in a common plane (r.m.s. deviations = 0.049 and 0.035 Å for the two mol­ecules in the asymmetric unit...

Sumario:The title compound, C(14)H(14)Si, crystallizes with two almost identical mol­ecules (r.m.s. deviation = 0.080 Å for all non-H atoms) in the asymmetric unit. All atoms of the silafluorene moiety lie in a common plane (r.m.s. deviations = 0.049 and 0.035 Å for the two mol­ecules in the asymmetric unit). The Si—C(meth­yl) bonds are significantly shorter [1.865 (4)–1.868 (4) Å] than the Si—C(aromatic) bonds [1.882 (3)–1.892 (3) Å]. Owing to strain in the five-membered ring, the endocyclic C—Si—C angles are reduced to 91.05 (14) and 91.21 (14)°.
