title: 3,6-Dichloro-catechol.
abstract: The title compound, C(6)H(4)Cl(2)O(2), exhibits a two-dimensional supra-molecular hydrogen-bonded network and forms a three-dimensional network supra-molecular structure via hydrogen bonds and π-π stacking of benzene rings. The π-π inter-actions are between the benzene rings of centrosymmetrically related mol-ecules, with centroid-centroid distances of 3.7676 (13) and 3.7107 (13) Å.
