The dihedral angle between naphthalene ring system and benzene ring is 70.62 (6)°. The nitro group is oriented in parallel with the adjacent carbonyl plane. The torsion angle of the carbonyl group and naphthalene ring is 54.68 (19)° (C-C-C-O), and that of nitro group and naphthalene ring is 54.26 (18)° (O-N-C-C). In the crystal, π-π inter-actions between naphthalene systems [centroid-centroid distances = 3.5633 (9), 3,5634 (9), and 3.9758(9) Å], C-H⋯O hydrogen bonds, inter-molecular N-O⋯Cl inter-actions [2.9937 (12) Å] and C-H⋯π contacts are observed.Acta crystallographica.
