چکیده
In the title compound, C(17)H(14)BrNO(5), the dihedral angle between the 3-bromo-substituted benzene ring and the 4,5-dimeth-oxy-2-nitro-phenyl ring is 15.2 (1)°. The dihedral angles between the mean plane of the propenone group and the mean planes of the 3-bromo-substituted benzene and 4,5-dimeth-oxy-2-nitro-phenyl rings are 6.9 (6) and 20.5 (5)°, respectively. Weak inter-molecular C-H⋯O inter-actions contribute to crystal stability and π-π inter-actions [centroid-centroid distances = 3.7072 (18) and 3.6326 (18) Å] are also observed.
