Action Figure 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 read more and C—H.

Cg π-ring stacking interactions [C—H.Cg distance = 3.377 (2) Å] are observed, which contribute to the stability of crystal packing.
