(±)-4,12,15,18,26-Pentahydroxy-13,17-dioxaheptacyclo[14.10.0.03,14.04,12.06,11.018,26.019,24]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
