The asymmetric unit of the title compound, C18H16O4, contains two crystallographically independent molecules. The anthraquinone ring systems are slightly bent with dihedral angles of 2.33 (8) and 13.31 (9)° between the two terminal benzene rings. In the crystal, the two independent molecules adopt slipped-parallel π-overlap with an average interplanar distance of 3.45 Å, forming a dimer; the centroid–centroid distances of the π–π interactions are 3.6659 (15)–3.8987 (15) Å. The molecules are also linked by C—H...O interactions, forming a tape structure along thea-axis direction. The crystal packing is characterized by a dimer-herringbone pattern.
