Abstract: The title compound, C₁₃H₉BrO, has been synthesized by the intramolecular Friedel-Crafts reaction of 1-(1-bromo-4-naphthyl)-3-chloropropan-1-one. There are two approximately planar [maximum deviations of 0.8 (2) and 0.4 (2) Å in the two molecules] molecules in the asymmetric unit. The dihedral angle between their mean planes is 19.72 (8)°. Weak intermolecular C-HO hydrogen bonding is present in the crystal structure.
