Notes:
The geometric structure and conformational properties of bis(trifluoromethylthio)methane, CH2(SCF3)2' were determined by gas electron diffraction. The main conformer (70 ± 15%) possesses C2 symmetry with dihedral angles Φ(SCSC) = 79.1(10)°. The second conformer possesses C1 symmetry. The following skeletal geometric parameters (distances ra [pm] and angles 〈α[°] with 3-σ uncertainties) were obtained: C—S 183.6(3), S—CF3, 179.3(3), S—C—S 112.1(6), and C—S—C 98.2(10). The geometric structures and relative conformational stabilities were well reproduced by ab initio calculations at the HF/3-21G* level.
