2017

The asymmetric unit of the title compound, C6H4Cl6O2·0.5H2O, 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 connectedviapairwise O—H...O hydrogen bonds. These dimers are connected by water molecules, resulting in layers parallel to theabplane.
