(S)-N-{1-[5-(4-Chloro­benzyl­sulfanyl)-1,3,4-oxadiazol-2-yl]eth­yl}-4-methyl­benzene­sulfonamide

The title compound, C(18)H(18)ClN(3)O(3)S(2), adopts by folding the form of a distorted disc. Inter­planar angles are 29.51 (7) and 63.43 (7)° from the five-membered ring to the aromatic systems and 34.80 (6)° between these two latter rings. The absolute configuration was confirmed by determination of the Flack parameter. In the crystal, the mol­ecules are linked by four hydrogen bonds, one classical (N—H⋯N) and three ‘weak’ (C—H⋯O), forming layers parallel to the ac plane; these are in turn linked in the third dimension by Cl⋯N [3.1689 (16) Å] and Cl⋯O [3.3148 (13) Å] contacts to the heterocyclic ring.
