(E)-3-(2,4-Dichlorophenyl)-1-(2-thienyl)prop-2-en-1-one

Abstract

In the title chalcone derivative, C13H8Cl2OS, the prop-2-en-1-one unit and the thio­phene and 2,4-dichloro­phenyl rings are each essentially planar. The inter­planar angle between the thio­phene and 2,4-dichloro­phenyl rings is 19.87 (6)°. Weak intra­molecular C—H⋯O and C—H⋯Cl inter­actions involving the prop-2-en-1-one unit generate an S(5)S(5) ring motif. In the crystal structure, mol­ecules are linked into head-to-tail zigzag chains along the a axis and adjacent chains are cross-linked. These cross-linked chains are arranged into sheets parallel to the ab plane. The crystal structure is stabilized by weak C—H⋯O, C—H⋯Cl and C—H⋯π inter­actions. A π–π inter­action was also observed with a centroid–centroid distance of 3.6845 (6) Å.
