چکیده
The title compound, C(13)H(9)ClOS, adopts an E configuration with respect to the C=C double bond of the propenone unit. The thienyl and benzene rings are slightly twisted from each other, making a dihedral angle of 6.38 (3)°. An intra-molecular C-H⋯O hydrogen bond generates an S(5) ring motif. A weak inter-molecular C-H⋯O inter-action, a short intra-molecular S⋯O contact [2.932 (2) Å] and two π-π inter-actions between the thienyl and benzene rings are observed. The centroid-centroid distances of the π-π inter-actions are 3.7899 (16) and 3.7891 (16) Å.
