Abstract The crystal structure of the title compound, CI2H14OS2, shows a 1, 3-dithiane ring adopting a chair conforma-tion with the 2-benzoyl group orientated axially. The carbonyl-O atom lies above the heterocycle, but is asymmetrically disposed with respect to both S atoms. Thus, the conformation can mainly be discussed on the basis of electrostatic dipole- dipole attraction (anomeric effect) of the C--S and C== O dipoles, together with exo- ...
