The gas-phase structure and some reactions of the bulky primary silane (Me(3)Si)(3)CSiH(3) and the solid-state structure of the bulky dialkyl disilane [(Me(3)Si)(3)CSiH(2)](2).
The molecular structure of the bulky primary silane, (Me(3)Si)(3)CSiH(3), in the gas phase has been determined by electron diffraction. Photolysis of (Me(3)Si)(3)CSiH(3) affords a convenient route to the bulky dialkyl disilane, [(Me(3)Si)(3)CSiH(2)](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)°.
