The molecular geometry of trichloromethyl sulphonyl chloride has been determined by electron diffraction. The sulphur bond configuration [rg (S = O) 1.421 ± 0.003 Å, rg (S—Cl) 2.021 ±0.005 Å, rg(S—C) 1.87±0.03Å, ∠O=S—C 108.3±0.7°, ∠C—S—Cl 97.9±0.8°, ∠O=S=O 121.5±0.9° and ∠ O=S—Cl 109.2 ± 0.6°] is consistent with the characteristic structural variations observed in the sulphone series. The barrier to internal rotation around the S—C bond was estimated to be between 3.5 and 6 kcal mol−1 by means of various procedures and assumptions.
