2,3-Dichlorobenzene-1,4-diol

Abstract

The achiral title compound, C6H4Cl2O2, crystallizes with O—H...O hydrogen bonding linking molecules into layers. Between layers there are chains of Cl...Cl...Cl interactions 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) interactions.
