Crystal structure and Hirshfeld surface analysis of (2E)-3-(2,4-di­chloro­phen­yl)-1-(2,5-di­chloro­thio­phen-3-yl)prop-2-en-1-one

摘要

The mol­ecular structure of the title compound, C13H6Cl4OS, consists of a 2,5-di­chloro­thio­phene ring and a 2,4-di­chloro­phenyl ring linked via a prop-2-en-1-one spacer. The dihedral angle between the 2,5-di­chloro­thio­phene ring and the 2,4-di­chloro­phenyl ring is 12.24 (15)°. The mol­ecule has an E configuration about the C=C bond and the carbonyl group is syn with respect to the C=C bond. The mol­ecular conformation is stabilized by intra­molecular C—H⋯Cl contacts, producing S(6) and S(5) ring motifs. In the crystal, the mol­ecules are linked along the a-axis direction through face-to-face π-stacking between the thio­phene rings and the benzene rings of the mol­ecules in zigzag sheets lying parallel to the bc plane along the c axis. The inter­molecular inter­actions 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%).
