2,7-Dimethoxy-1-(4-nitrobenzoyl)-naphthalene

In the title compound, C19H15NO5, the dihedral angle between the naphthalene ring system and the benzene ring is 61.97 (5)degrees. The dihedral between the naphthalene ring system and the bridging carbonyl C-C(=O)-C plane is 54.68 (6)degrees, far larger than that [12.54 (7)degrees] between the phenyl group and the bridging carbonyl group. The nitro group and the phenyl ring are almost coplanar [O-N-C-C torsion angle = 2.94 (19)degrees]. In the crystal, molecules are linked by C-H center dot center dot center dot pi interactions and the phenyl rings are involved in a centrosymmetric pi-pi interaction with a perpendicular distance of 3.523 angstrom and a lateral offset of 1.497 angstrom. In addition, weak intermolecular C-H center dot center dot center dot O hydrogen bonds are formed between an H atom of one methoxy group and a nearby carbonyl O atom.
