N-[2-(4-Chlorophenyl)-5-methyl-4-oxo-1,3-thiazolidin-3-yl]pyridine-3-carboxamide (original) (raw)

The title compound, C 16 H 14 ClN 3 O 2 S, crystallizes with two molecules in the asymmetric unit. In the 1,3-thiazolidine rings, the carbonyl O atoms, the S atoms, the methyl groups and the ring carbon attached to the methyl groups are disordered with occupancy ratios of 0.509 (7):0.491 (7) in one molecule and 0.464 (14):0.536 (14) in the other. The crystal structure is stabilized by intermolecular N-HÁ Á ÁN, C-HÁ Á ÁO hydrogen bonds and C-HÁ Á ÁCl interactions. In addition, there is astacking interaction [centroid-centroid distance = 3.794 (3) Å ] between the benzene and pyridine rings.
