title: (2E)-3-(3-Bromo-4-meth-oxy-phen-yl)-1-(4-methyl-phen-yl)prop-2-en-1-one.
abstract: 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.
