Abstract

In the title compound, C20H16BrNO2, the dihedral angle between the quinolone ring system mean plane (r.m.s. deviation = 0.018 Å) and the phenyl ring bridged by the ethynyl group, is 25.44 (14)°. There is an intra-molecular C-H⋯O hydrogen bond forming an S(6) ring motif. In the crystal, mol-ecules are linked via C-H⋯O hydrogen bonds forming chains propagating along the b-axis direction.

Keywords: crystal structure; hydrogen bonding; quinoline; quinoline-4-carboxyl­ate.
