Özet

In the title compound, C20H14N2O2, the hydroxybenzene ring is almost perpendicular to the mean plane of the naphthalene ring system, making a dihedral angle of 85.56 (4)degrees. The 4H-pyran ring fused with the naphthalene ring system has a flattened boat conformation. In the crystal, O-H center dot center dot center dot N and N-H center dot center dot center dot O hydrogen bonds link the molecules into a supramolecular layer in the bc plane; N-H center dot center dot center dot pi interactions also contribute to this arrangement. The layers are linked by weak by C-H center dot center dot center dot pi and pi-pi [inter-centroid separation = 3.8713 (7) angstrom] interactions.
