(+)-N-[2-(4-Chlorophenyl)propanoyl]bornane-10,2-sultam

In the molecular structure of the title compound, C19H24ClNO3S, the six-membered ring of the bornane unit shows a boat form, while the five-membered ring of the sultam unit adopts a twist form. Intramolecular C—H⋯N and C—H⋯O interactions are observed. In the crystal structure, molecules are connected by intermolecular C—H⋯O hydrogen bonds into a chain running along the b axis. The crystal was a partial inversion twin with a twin ratio of 0.73 (1):0.27 (1).
