Abstract

The molecular structure of the bulky primary silane, (Me₃Si)₃CSiH₃, in the gas phase has been determined by electron diffraction. Photolysis of (Me₃Si)₃CSiH₃ affords a convenient route to the bulky dialkyl disilane, [(Me₃Si)₃CSiH₂]₂, which is the first 1,2-dialkyldisilane to be structurally characterised by single-crystal X-ray diffraction. The disilane has an unusually large Si–Si–C angle of 120.05(9)°.
