The title compound, C17H12O4, was synthesized from the dye alizarin. The dihedral angle between the mean plane of the anthraquinone ring system (r.m.s. deviation = 0.039 Å) and the dioxepine ring is 16.29 (8)°. In the crystal, the molecules are linked by C—H...O hydrogen bonds, forming sheets lying parallel to the ab plane. The sheets are connected through π–π and C=O...π interactions to generate a three-dimensional supramolecular network. Hirshfeld surface analysis was used to investigate intermolecular interactions in the solid-state: the most important contributions are from H...H (43.0%), H...O/O...H (27%), H...C/C...H (13.8%) and C...C (12.4%) contacts.
