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-H...O hydrogen bonds, weak C-H...O hydrogen bonds and C-H...[pi] inter­actions link the mol­ecules into a three-dimensional supra­molecular architecture.
