On the molecular structure of methane sulfonyl chloride as studied by electron diffraction

The molecular structure of methane sulfonyl chloride in the vapors was studied by electron diffraction. Three models were found in excellent agreement with experiment differing largely in the values of the O–S–O angle and the mean amplitudes of vibration for some of the nonbonded distances. The favored model has the following geometrical parameters (with their errors parenthesized): C–H 1.101 (0.013) Å, S–O 1.424 (0.003) Å, S–C 1.763 (0.005) Å, Cl–S 2.046 (0.004) Å, ∠ Cl–S–C 101.0° (1.5°), ∠ O–S–O 120.8° (2.4°), ∠ Cl–S–O 107.1° (0.7°), ∠ H–C–H 112.0° (2.0°). The structure of SO2Cl2, CH3SO2Cl, and (CH3)2SO2 are compared.
