(E)-3-(2-Bromophenyl)-1-(3,4-dimethoxyphenyl)prop-2-en-1-one

Abstract

The crystal structure of the title compound, C17H15BrO3, a chalcone derivative, exhibits two crystallographically independent molecules per asymmetric unit showing an E conformation about the ethylene double bond. In each molecule, the two phenyl rings are almost coplanar: the mean planes make dihedral angles of 9.3 (2) and 19.4 (2)°. In the crystal, molecules are linked through weak intermolecular C—H...O hydrogen bonds.
