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-HO hydrogen bonds. The overall three-dimesional supramolecular architecture is stabilized by C-ClO halogen bonding, with a ClO separation of 3.139 (3) Å and a C-ClO angle of 162.5 (2)°.
