(E)-3-(2,4-Dichloro-phen-yl)-1-(2-thien-yl)prop-2-en-1-one.

ABSTRACT: In the title chalcone derivative, C(13)H(8)Cl(2)OS, the prop-2-en-1-one unit and the thio-phene and 2,4-dichloro-phenyl rings are each essentially planar. The inter-planar angle between the thio-phene and 2,4-dichloro-phenyl rings is 19.87?(6)°. Weak intra-molecular C-H?O and C-H?Cl inter-actions involving the prop-2-en-1-one unit generate an S(5)S(5) ring motif. In the crystal structure, mol-ecules 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?? inter-actions. A ?-? inter-action was also observed with a centroid-centroid distance of 3.6845?(6)?Å.
