چکیده
The title compound, C(5)H(8)Cl(2)O(2), represents a meso isomer crystallizing in a chiral space group with two mol-ecules per asymmetric unit. The mol-ecules form helical associates with a pitch of 6.31 Å along the a axis via O-H⋯O hydrogen bonds. The overall three-dimesional supra-molecular 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)°.
