(2,7-Dimethoxynaphthalen-1-yl)(3-nitrophenyl)methanone

The title compound, C19H15NO5, has an intramolecular C—H...O=C hydrogen bond between a naphthalene H atom and the O atom of the carbonyl group. The interplanar angle between the naphthalene ring system and the benzene ring is 69.59 (5)°. The dihedral angle between the bridging carbonyl C—C(=O)—C plane and the naphthalene ring system is 61.02 (6)°, which is far larger than that between the bridging carbonyl plane and the benzene ring [12.68 (7)°]. The nitro group is slightly out of the plane of the benzene ring [O—N—C—C torsion angle = 4.97 (17)°]. In the crystal, the packing is mainly stabilized by C—H...O interactions between an H atom of the benzene ring and an O atom of the nitro group.
