Abstract: The title compound, C24H14O9·2CH3OH, displays a chair-shaped form. The two dihydroindenone ring systems are located above and below the central fused-ring system, the dihedral angles between the mean planes of dihydroindenone ring systems and the mean plane of central fused-ring system are 67.91 (5) and 73.52 (4)°, respectively. In the crystal, extensive O-HO hydrogen bonds, weak C-HO hydrogen bonds and C-H interactions link the molecules into a three-dimensional supramolecular architecture.
