(E)-1-(2,5-Dichloro-3-thienyl)-3-(3,4-dimethoxyphenyl)prop-2-en-1-one

In the title compound, C15H12Cl2O3S, the prop-2-en-1-one (enone) fragment is almost planar [C-C-C-O = 2.2 (4)degrees] and it subtends dihedral angles of 11.9 (2) and 11.0 (2)degrees with the thiophene and benzene rings, respectively. The dihedral angle between the aromatic rings is 3.47 (16)degrees. In the crystal, weak C-H center dot center dot center dot O and C-H center dot center dot center dot Cl interactions link the molecules, leading to R-2(2)(14), R-2(2)(24) and C(11) supramolecular motifs occurring within the three-dimensional network. Weak aromatic pi-pi stacking [centroid-centroid separations = 3.6823 (15) and 3.8722 (15) angstrom] may also help to consolidate the packing.
