Abstract:

In the chalcone title compound, C18H17BrO4, the dihedral angle between the mean planes of the 2-bromo- and 3,4,5-trimethoxy-substituted benzene rings is 89.3 (1)°. The angles between the mean plane of the prop-2-en-1-one group and the 2-bromophenyl and 3,4,5-trimethoxyphenyl ring planes are 59.7 (1) and 40.5 (8)°, respectively. While no classical hydrogen bonds are present, three weak intermolecular C—H...O interactions and weak C—H...Br and C—H...Cg π-ring stacking interactions [C—H...Cg distance = 3.377 (2) ] are observed, which contribute to the stability of crystal packing.
