Abstract: In the title compound, C23H20N2O6, the fused pyrone and pyran rings each adopt a sofa conformation. The dihedral angle between the mean planes of the pyran and phenyl rings is 61.9 (1)°. In the crystal, molecules are linked by two pairs of C-HO hydrogen bonds, forming dimers. These dimers are linked via a third C-HO hydrogen bond, forming a two-dimensional network parallel to (10-2).
