%X 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)¡ã. In the crystal, molecules are linked by two pairs of C¡ªH...O hydrogen bonds, forming dimers. These dimers are linked via a third C¡ªH...O hydrogen bond, forming a two-dimensional network parallel to (10-2).
