In the title compound, C(18)H(12)BrClO(3), the naphthalene ring system and the benzene ring make a dihedral angle of 82.18 (9)°. 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. 60.91 (16)° versus 13.94 (16)°. In the crystal structure, two π-π inter-actions formed between the naphthalene ring systems [centroid-centroid distances of 3.8014 (13) and 3.9823 (13) Å] and inter-molecular O-H⋯O and C-H⋯O hydrogen bonds are present.
在标题化合物C₁₈H₁₂BrClO₃中，萘环体系与苯环形成的二面角为82.18 (9)°。中心C=O基团周围的构象使得C=O键向量与萘环体系平面形成的角度大于与苯环平面形成的角度，即60.91 (16)°对13.94 (16)°。在晶体结构中，萘环体系之间形成了两种π-π相互作用（质心-质心距离分别为3.8014 (13) 和3.9823 (13) Å），并且存在分子间O-H⋯O和C-H⋯O氢键。
