| Abstract: | Crystals of the title compound H2C(SiPh3)2 are triclinic, space group P, with a = 9.290(2), b = 12.128(4), c = 16.882(4) Å, α = 62.08(1), β = 106.88(1), γ = 117.28(2)° and Z = 2. The central skeletal angle SiCSi is 128.8(7)°. The structures of the molecules H2C(SiR3)2 (R = H, CH3, and Ph) are compared and discussed: a simple model for the skeletal geometry of species H2C(MR3)2 is proposed, and tested against experimental data and theoretical calculations. |
