(E)-1-(2-Bromo-phen-yl)-3-(2,5-dimeth-oxy-phen-yl)prop-2-en-1-one.

ABSTRACT: The title compound, C(17)H(15)BrO(3), is a chalcone with the 2-bromo-phenyl and 2,5-dimeth-oxy-phenyl rings bonded at opposite ends of a propene group. The dihedral angle between the mean planes of the ortho-bromo and ortho,meta-dimeth-oxy-substituted benzene rings is 77.3?(1)°. The dihedral angles between the mean plane of the prop-2-ene-1-one group and the mean planes of the 2-bromo-phenyl and 2,5-dimeth-oxy-phenyl rings are 58.6?(1) and 30.7?(4)°, respectively. Weak C-H?O, C-H?Br and ?-? stacking inter-molecular inter-actions [centroid-centroid distance = 3.650?(2)?Å] are present in the structure.
