Vinyl dichlorosilane and vinyl dibromosilane (H2C=CH-SiHX2, X = Cl, Br): Conformational structure and vibrational properties determined by gas-phase electron diffraction, ab initio molecular orbital calculations, and variable-temperature Raman spectroscopy

The molecular structures, conformations, vibrational spectra, and torsional potentials of vinyl dichlorosilane (VDC) H2C=CH-SiHCl2, and vinyl dibromosilane (VDB) H2C=CH-SiHBr2, have been studied using gas-phase electron diffraction (GED) data at 23-25°C and variable-temperature Raman spectroscopy, together with ab initio molecular orbital calculations. The GED data were handled by a dynamic theoretical model using a cosine Fourier potential function in describing the torsional coordinate. According to the GED refinements, these molecules exist in the gas phase at room temperature as a mixture of two minimum energy conformers, syn (torsional angle φ(CCSiH) = 0°) and gauche (torsional angle φ(CCSiH) ? 120°). Relevant structural parameters for syn-VDC are as follows: Bond lengths (r(g)): r(Si-C) = 1.847(5) A?, r(Si-Cl) = 2.042(2) A?, r(C=C) = 1.357(7) A?. Bond angles (angle(α)): angle CSiCl = 110.3(6)°, angle CCSi = 121.8°(calc.). Relevant structural parameters for syn-VDB are as follows: bond lengths (r(g)): r(Si-C)= 1.827(9) A?, r(Si-Br) = 2.206(2) A?, r(C=C) = 1.366(10) A?. Bond angles (angle α): angle CSiBr = 110.1(8)°, angle CCSi=121.7°(calc.). Uncertainties are given as 2σ (σ includes estimates of uncertainties in voltage/height measurements and correlation in the experimental data). From the variable-temperature Raman investigation in the liquid phase, the energy differences are: VDC, ΔE°(S-G) = + 0.11 ± 0.06 kcal mol-1; VDB, ΔE°(S-G) = + 0.23 ± 0.07 kcal mol-1. The Raman energies are average values obtained from two separate line doublets for each molecule, and they have been used in the GED least-squares refinements as valuable constraints.
