(8-Bromo-2-hydroxy-7-methoxy-1-naph-thyl)(4-chlorobenzoyl)methanone.

ABSTRACT: 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 ?-? 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.

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)  ...[more]
