Molecular structure of hexakis(trifluoromethylthio)ethane

Abstract

The molecular structure of C₂(SCF₃)₆ has been investigated by electron-diffraction studies on the vapour. The best agreement between experiment and model is obtained with local C₁ symmetry for the C(SCF₃)₃ groups and C_i overall symmetry for the molecule. The following geometric parameters for the C₂S₆ skeleton have been determined (r_g values): C–C 1.624(37). C–S 1.839(12)Å, S–C–S 113.9(0.3)°, where the error limits are three times the standard deviations. Other geometric parameters and vibrational amplitudes are given. The most striking result of this investigation is the long C–C bond.
