Abstract

In the title compound, C15H13ClO3S, the chlorothiophene and dimethoxyphenyl groups are linked by a prop-2-en-1-one group. The C C double bond exhibits an E conformation. The molecule is non-planar, with a dihedral angle of 31.12 (5)' between the chlorothiophene and dimethoxyphenyl rings. The methoxy group at position 3 is coplanar with the benzene ring to which it is attached, with a C—O—C—C torsion angle of -3.8(3)'. The methoxy group attached at position 2 of the benzene ring is in a (+)synclinal conformation, as indicated by the C—O—C—C torsion angle of -73.6 (2)'. In the crystal, two different C—H...O intermolecular interactions generate chains of molecules extending along the b axis.
