trans-7,7-Diphenyl-7-silabicyclo[3.3.0]octan-3-one p-Tosylhydrazone Tetrahydrofuran Solvate

The structure of the title compound has been determined as a tetrahydrofuran solvate, C₂₆H₂₈N₂O₂SSi·C₄H₈O, at 193 K. This compound, which crystallizes in the monoclinic space group C2/c, is disordered. The distances between the bridgehead atoms were restrained to be 1.510 ± 0.015 Å and refined to 1.515 (11) (C1A-C5A) and 1.505 (12) Å (C1B-C5B). The trans-fusion of the system results in a rather flat geometry, with the two cyclopentane rings adopting envelope conformations.
