Description
Summary: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, mol-ecules are linked by C-H⋯π inter-actions and the phenyl rings are involved in a centrosymmetric π-π inter-action with a perpendicular distance of 3.523 Å and a lateral offset of 1.497 Å. In addition, weak inter-molecular C-H⋯O hydrogen bonds are formed between an H atom of one meth-oxy group and a nearby carbonyl O atom.
