ABSTRACT In the title compound, C19H14BrClO3, the naphthalene ring system and the benzene ring make a dihedral angle of 77.36 (10)°. The conformation around the central C=O group is such that the C=O bond vector forms a larger angle to the plane of the naphthalene ring system than to the plane of the benzene ring, viz. 75.73 (15)° versus 2.33 (17)°. In the crystal structure, a π–π interaction is formed between naphthalene ring systems, with a centroid–centroid distance of 3.8363 (14) Å and a lateral offset of 1.606 Å. Intermolecular C—H...Br and C—H...O hydrogen bonds and a C—H...π contact are present in the crystal structure.
