title: 2,3-Dichloro-benzene-1,4-diol.
abstract: The achiral title compound, C(6)H(4)Cl(2)O(2), crystallizes with O-H⋯O hydrogen bonding linking mol-ecules into layers. Between layers there are chains of Cl⋯Cl⋯Cl inter-actions with alternating distances of 3.274 (2) and 3.742 (2) Å. Augmenting this arrangement there are also C-H⋯Cl (2.97 and 3.17 Å) and Cl⋯π (shortest distances 3.40 and 3.54 Å) inter-actions.
