title: (4-Chloro-phen-yl)(3,8-dibromo-2-hydr-oxy-7-meth-oxy-1-naphth-yl)methanone.
abstract: In the title compound, C(18)H(11)Br(2)ClO(3), an intra-molecular O-H⋯O=C hydrogen bond occurs, forming a six-membered ring. The naphthalene ring system and the benzene ring make a dihedral angle of 57.36 (9)°. The central carbonyl C-(C=O)-C group is twisted away from the naphthalene ring system and the benzene ring by 18.61 (15) and 26.25 (16)°, respectively. In the crystal structure, two inter-molecular Br⋯Cl close contacts [3.4927 (7) and 3.4325 (7) Å] are observed.
