In the title compound, CHO, 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 meth-oxy groups at the and 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 (14) inversion dimers, which are linked by another pair of C-H⋯O hydrogen bonds to form [210] chains in the crystal.
在标题化合物CHO中，中心吡喃环呈信封构象，苯环与萘环体系之间的二面角为88.31 (1)°。苯环和位置的甲氧基分别以105.9 (4)°和9.5 (5)°的C-C-O-C扭转角向环倾斜。在晶体中，成对的C-H⋯O氢键形成(14)反演二聚体，这些二聚体通过另一对C-H⋯O氢键相连，在晶体中形成[210]链。
