[(1R,3S)-2,2-Dichloro-3-(hydroxymethyl)cyclopropyl]methanol

Abstract

The title compound, C5H8Cl2O2, represents a meso isomer crystallizing in a chiral space group with two molecules per asymmetric unit. The molecules form helical associates with a pitch of 6.31 Å along the a axis via O—H...O hydrogen bonds. The overall three-dimesional supramolecular architecture is stabilized by C—Cl...O halogen bonding, with a Cl...O separation of 3.139 (3) Å and a C—Cl...O angle of 162.5 (2)°.
