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

In the title compound, C(19)H(15)NO(5), the dihedral angle between the naphthalene ring system and the benzene ring is 61.97 (5)°. The dihedral between the naphthalene ring system and the bridging carbonyl C—C(=O)—C plane is 54.68 (6)°, far larger than that [12.54 (7)°] 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)°]. In the crystal, mol­ecules are linked by C—H⋯π inter­actions and the phenyl rings are involved in a centrosymmetric π–π inter­action with a perpendicular distance of 3.523 Å and a lateral offset of 1.497 Å. In addition, weak inter­molecular C—H⋯O hydrogen bonds are formed between an H atom of one meth­oxy group and a nearby carbonyl O atom.
