چکیده
The overall shape of the mol-ecule of the title compound, C(17)H(15)BrO(2), can be described by the dihedral angles between three planar fragments: 1-bromo-2-meth-oxy-phenyl ring [maximum deviation = 0.003 (2) Å], the central prop-2-en-1-one chain [maximum deviation = 0.005 (2) Å], and the methyl-phenyl ring [maximum deviation = 0.004 (2) Å]. The terminal planes are twisted by 10.37 (12)°, while the central plane is almost coplanar with the methyl-phenyl ring [3.30 (13)°], but the dihedral angle with the other phenyl ring is significantly larger [8.76 (16)°]. In the crystal, mol-ecules are linked into chains along [001] by three C-H⋯O hydrogen bonds. These chains inter-act with each other by means of weak π-π contacts [centroid-centroid distances = 3.73 (1) and 3.44 (1) Å]. An inter-molecular C-H⋯Br inter-action also occurs.

The mean planes of the benzene and pyridine rings in the title compound, C(15)H(12)BrNO(2), are nearly coplanar, subtending an angle of 2.8 (8)°. The prop-2-en-1-one group is also in the plane of these rings with an N-C-C-O torsion angle of 179.6 (3)°. A weak C-H⋯Br inter-molecular inter-action contributes to the crystal packing, creating a chain-like structure along the a axis.
