Abstract
Abstract The molecular structure of methane sulphonyl fluoride in the vapour state was studied by electron diffraction. Assuming a value of 2.480A˚for the distance between the oxygen atoms from a microwave determination, the following geometrical parameters (r a structure) have been obtained: r(C-H) = 1.093±0.010A, r(S-O) = 1.410±0.003A, r(S-F) = 1.561 ±0.004A, r(S-C) = 1.759±0.006A, ∠F-S-C = 98.2±1.5°, ∠-S-F = 106.2±0.4°, ∠-O-S-O = 123.1 ±1.5° and ∠H-C-H = 112.9±1.9°. All the observed variations in the molecular geometries of (CH 3 ) 2 SO 2 , CH 3 SO 2 Cl, CH 3 SO 2 F and SO 2 F 2 may be accounted for by the valence shell electron pair repulsion theory. It is particularly advantageous to combine electron diffraction and microwave data in studying sulphone molecular geometries.
