| description | In the title compound, C21H18O4, the central pyran ring is in an envelope conformation and the dihedral angle between the benzene ring and naphthalene ring system is 88.31 (1)°. The methoxy groups at the ortho and meta positions of the benzene ring are tilted to the ring with C—C—O—C torsion angles of 105.9 (4) and 9.5 (5)°, respectively. In the crystal, pairwise C—H...O hydrogen bonds form R22(14) inversion dimers, which are linked by another pair of C—H...O hydrogen bonds to form [210] chains in the crystal. |
