2,3-Dichloro-5,8-dimethoxy-1,4-naphthoquinone

Abstract

In the crystal structure of the title compound, C12H8Cl2O4, molecules crystallize in planes parallel to (-204) with an interplanar distance of 3.288 (2) Å [centroid–centroid distance = 3.819 (2) and slippage = 1.932 (2) Å]. The structure features C—H...O interactions involving methoxy and aromatic H atoms and the carbonyl O atoms as well as a C—H...Cl interaction involving an aromatic H atom. In addition there are short interhalogen contacts between adjoining molecules [Cl...Cl = 3.3709 (5) Å].
