Abstract
In the octahydroxanthenedione unit of the title compound, C31H27NO6, the central dihydropyran ring shows an envelope conformation, while the bilateral cyclohexene and cyclohexane rings adopt a half-boat conformation and a chair conformation, respectively. The nitrobenzene ring is twisted with respect to the two benzene rings, making dihedral angles of 63.1 (1) and 63.0 (1)°. In the crystal, O—H...O hydrogen bonds link the molecules into supramolecular chains propagating along thea-axis direction.
