Crystal structure and Hirshfeld surface analysis of (2)-3-(2,4-di-chloro-phen-yl)-1-(2,5-di-chloro-thio-phen-3-yl)prop-2-en-1-one.

The mol-ecular structure of the title compound, CHClOS, consists of a 2,5-di-chloro-thio-phene ring and a 2,4-di-chloro-phenyl ring linked a prop-2-en-1-one spacer. The dihedral angle between the 2,5-di-chloro-thio-phene ring and the 2,4-di-chloro-phenyl ring is 12.24 (15)°. The mol-ecule has an configuration about the C=C bond and the carbonyl group is with respect to the C=C bond. The mol-ecular conformation is stabilized by intra-molecular C-H⋯Cl contacts, producing (6) and (5) ring motifs. In the crystal, the mol-ecules are linked along the axis direction through face-to-face π-stacking between the thio-phene rings and the benzene rings of the mol-ecules in zigzag sheets lying parallel to the plane along the axis. The inter-molecular inter-actions in the crystal packing were further analysed using Hirshfield surface analysis, which indicates that the most significant contacts are Cl⋯H/ H⋯Cl (20.8%), followed by Cl⋯Cl (18.7%), C⋯C (11.9%), Cl⋯S/S⋯Cl (10.9%), H⋯H (10.1%), C⋯H/H⋯C (9.3%) and O⋯H/H⋯O (7.6%).
