Abstract

Crystals of the title compound are monoclinic, space group
P21, with a = 1.0018(2), b = 0.9722(2), c = 0.6262(1) nm, fJ = 102.32(1)° and Z = 2. The structure was solved by direct methods using 1113 reflections with I 2': 20 (I) and refined to a conventional R index
of 0.051. The heterocyclic four-membered ring is bent and has a
puckering angle of 18.7(7)°. The dihedral angle between the best
planes of the B-propiothiolactone and benzene ring is 70.2(3)°.
Discrete molecules are connected along the b axis by intermolecular
hydrogen bonds N--H ... O of 309.5(9) pm.
