Abstract
In the title compound, C22H18O6, the dimethoxy-substituted naphthalene ring system is twisted relative to the 4H-chromenon skeleton by 88.96 (3)°. The two methoxy substituents are tilted from the naphthalene ring system by 1.4 (4) and 113.0 (2)°, respectively. An intramolecular O—H...O hydrogen bond closes anS(5) ring motif. In the crystal, pairs of O—H...O hydrogen bonds form inversion dimers withR22(10) loops and C—H...O interactions connect the dimers into [010] chains.
