title: N-(4-Chloro-phen-yl)-1-(5-{[(2-phenyl-ethen-yl)sulfon-yl]meth-yl}-1,3,4-oxadiazol-2-yl)methane-sulfonamide.
abstract: In the title compound, C(18)H(16)ClN(3)O(5)S(2), 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 C(ox)-C-S-C (ox = oxadiazole) torsion angles are 89.3 (5) and -69.1 (3)°, respectively. A short intra-molecular C-H⋯O contact closes an S(6) ring. In the crystal, mol-ecules are linked by N-H⋯O hydrogen bonds, generating C(10) chains propagating in [001]. The packing is consolidated by C-H⋯O, C-H⋯π and very weak aromatic π-π stacking inter-actions [centroid-centroid separation = 4.085 (2) Å].
