title: Crystal structure of ethyl 6-bromo-2-[(E)-2-phenyl-ethen-yl]quinoline-4-carboxyl-ate.
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.
