Abstract
The title compound, C17H14BrNO2, was synthesized by the treatment of 5,7-dimethoxy-4-phenylquinolin-2-one with phosphoryl bromide in a Vilsmeier-type reaction. There are two independent molecules (A and B) in the asymmetric unit which differ by 11.2° in the orientation of the 4-phenyl ring with respect to the planar quinoline ring system [dihedral angles = 55.15 (8) and 66.34 (8)° in molecules A and B, respectively]. In the crystal structure, the independent molecules are linked via C—H⋯N and C—H⋯O hydrogen bonds, forming centrosymmetric tetrameric units which are cross-linked through C—H⋯π and C—Br⋯π interactions with Br⋯centroid distances of 3.4289 (8) and 3.5967 (8) Å.
