(±)-4,12,15,18,26-Penta­hydroxy-13,17-dioxahepta­cyclo­[14.10.0.0^3,14.0^4,12.0^6,11.0^18,26.0^19,24]hexa­cosa-1,3(14),6(11),7,9,15,19,21,23-nona­ene-5,25-dione methanol disolvate

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...π inter­actions link the mol­ecules into a three-dimensional supra­molecular architecture.
