Crystal structure and Hirshfeld surface analysis of E 3 2 chlorophenyl 1 2 5 dichlorothiophen 3 yl prop 2 en 1 one.

The dihedral angle between the 2,5-di­chloro­thio­phene and 2-chloro­phenyl rings is 9.69?(12)°. 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 two intra­molecular C—H?Cl contacts and one intra­molecular C—H?O contact, forming S(5)S(5)S(6) ring motifs. In the crystal, the mol­ecules are linked along the a-axis direction through van der Waals forces and along the b axis by face-to-face ?-stacking between the thio­phene rings and between the benzene rings of neighbouring mol­ecules, forming corrugated sheets lying parallel to the bc plane. 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 (28.6%), followed by C?H/H?C (11.9%), C?C (11.1%), H?H (11.0%), Cl?Cl (8.1%), O?H/H?O (8.0%) and S?H/H?S (6.6%).enAttribution-NonCommercial-ShareAlike 4.0 Internationalinfo:eu-repo/semantics/openAccessCrystal structure2,5- di­chloro­thio­phene ring2-chloro­phenyl ringE configurationIrshfeld surface analysisArticle75212412810.1107/S2056989018018066Q3N/A
