Özet
In the title compound, C21H16N2O2, the methoxybenzene ring is almost perpendicular to the mean plane of the naphthalene ring system, making a dihedral angle of 83.62 (5)degrees. The 4H-pyran ring fused with the naphthalene ring system is almost planar [maximum deviation = 0.033 (1) angstrom]. In the crystal, molecules are linked into inversion dimers by pairs of N-H center dot center dot center dot N hydrogen bonds. N-H center dot center dot center dot O hydrogen bonds connect the dimers, forming a helical supramolecular chain along the a-axis direction. The crystal packing also features C-H center dot center dot center dot pi interactions.
