title: (8-Bromo-2,7-dimeth-oxy-1-naphth-yl)(4-chloro-phenyl)methanone.
abstract: In the title compound, C(19)H(14)BrClO(3), 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 inter-action is formed between naphthalene ring systems, with a centroid-centroid distance of 3.8363 (14) Å and a lateral offset of 1.606 Å. Inter-molecular C-H⋯Br and C-H⋯O hydrogen bonds and a C-H⋯π contact are present in the crystal structure.
