(2E)-1-(5-Chloro­thio­phen-2-yl)-3-(2,3-dimeth­oxy­phen­yl)prop-2-en-1-one

摘要

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.
