N-(4-Chlorophenyl)-1-(5-{[(2-phenyl-ethenyl)sulfonyl]methyl}-1,3, 4-oxadiazol-2-yl)methanesulfonamide

Abstract

In the title compound, C18H16ClN3O 5S2, the dihedral angles between the oxadiazole ring and the phenyl and chloro-benzene rings are 23.4 (2) and 45.4 (2)°, respectively. The C - S - N - C and Cox - C - S - C (ox = oxadiazole) torsion angles are 89.3 (5) and - 69.1 (3)°, respectively. A short intramolecular C - H···O contact closes an S(6) ring. In the crystal, molecules are linked by N - H···O hydrogen bonds, generating C(10) chains propagating in [001]. The packing is consolidated byC - H···O, C - H···φ and very weak aromatic φ-φ stacking interactions [centroid-centroid separation = 4.085 (2) Å].
