(+)-(1R,2S,3S,4S)-2-Chloro-3-(phenylselanyl)cyclohexane-1,4-diol

Abstract

Key indicators: single-crystal X-ray study; T = 223 K; mean (C-C) = 0.003 Å; R factor = 0.029; wR factor = 0.077; data-to-parameter ratio = 19.3.The cyclohexyl ring in the title compound, C 12 H 15 ClO 2 Se, has a chair conformation with the 4-hydroxy group occupying an axial position; the other non-H substituents occupy equatorial positions. Molecules aggregate via O-HÁ Á ÁO hydrogen bonds into a supramolecular helical chain.
