rac-1,1,1,6,6,6-Hexa-chloro-hex-3-yne-2,5-diol hemihydrate

摘要

The asymmetric unit of the title compound, C6H4Cl6O20.5H2O, contains one molecule of 1,1,1,6,6,6-hexachlorohex-3-yne-2,5-diol and half a water molecule located on a twofold rotation axis. In the crystal, pairs of hexachlorohexynediol molecules form centrosymmetric dimers connected via pairwise O—HO hydrogen bonds. These dimers are connected by water molecules, resulting in layers parallel to the ab plane.
