Abstract The molecular geometry of triflic acid is characterized by the following bond lengths (rg) and bond angles from an electron diffraction study: S-C 183.3±0.5, F-C 133.2 ±0.2, S=O 141.8±0.2, S-O 155.8±0.3 pm, S-C-F 110.3 ±0.3, F-C-F 108.6 ±0.3, C-S=O 105.4±1.1, C-S-O 102.3 ±2.3, O-S= O 109.9±0.7, and O=S=O 122.0 ±1.3°. The heavy-atom-skeleton is staggered with respect to the rotation about the S-C bond with an estimated barrier of rotation of 15 kJ mol-1.

Abstract An electron diffraction investigation yielded the following geometric parameters for trifluoromethyl sulphonyl chloride rg(C-F ) 1.326(4), rg(S=0 ) 1.416(7), rg(S-Cl) 2.016(5), rg(S-C) 1.857(6) Å, ∢ O= S - C 108.3(7)°, ∢ C-S-Cl 98.7(4)°, ∢ O = S = O 122.4(10),° ∢ O = S - Cl 108.3(3)°, ∢ F -C-F 109.9(3)°. The S - C bond is in CF3SO2Cl by almost 0.1 Å longer than in CH3SO2Cl.
