Abstract
The title xanthone derivative, C26H30O6, extracted from the bark of Cratoxylum glaucum, adopts an almost planar fused ring system with a maximum deviation of 0.078 (1) Å. In the crystal, molecules are linked into inversion dimers by pairwise C - H...O interactions. These dimers are further linked into chains by C - H...π and C - O...π interactions. Computational chemistry revealed that the overall stabilization energy of the packing is dominated by dispersion energy. The conformations of related xanthones are also surveyed.
