摘要：

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)degrees. 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) degrees, respectively. While no classical hydrogen bonds are present, three weak intermolecular C-H center dot center dot center dot O interactions and weak C-H center dot center dot center dot Br and C-H center dot center dot center dot Cg pi-ring stacking interactions [C-H center dot center dot center dot Cg distance = 3.377 (2) angstrom] are observed, which contribute to the stability of crystal packing.
