1-(2,5-Dichloro-3-thien-yl)ethanone: infinite sheets mediated by O⋯Cl halogen bonds.

In the title compound, C6H4Cl2OS, the acetyl group is almost coplanar with the thio­phene ring [dihedral angle = 4.01 (2)°]. In the crystal, short inter­molecular O⋯Cl contacts [2.9494 (14) and 3.1191 (14) A] link the mol­ecules into infinite (100) sheets and aromatic π–π stacking [centroid–centroid separation = 3.5422 (10) A] consolidates the packing.
