Abstract
In the title compound, C19H14ClNO5, the aroyl group is attached to the naphthalene ring system with a non-coplanar configuration. 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 interactions between naphthalene systems [centroid–centroid distances = 3.5633 (9), 3,5634 (9), and 3.9758(9) Å], C—H...O hydrogen bonds, intermolecular N—O...Cl interactions [2.9937 (12) Å] and C—H...π contacts are observed.
