Abstract

(S)-a-(p-Bromobenzenesulphonamido)-{J-propiothiolactone,
C9H8N03S2Br, crystallizes in the orthorhombic system with a =
= 1.0125(2), b = 1.2439(1) and c = 0.9304(3) nm, Z = 4 in space group
P212121• The compound is isostructural with the analogous chloro
derivative. The crystal structure has been refined from diffractometer
data to conventional R and Ra values of 0.045 and 0.048 for
2277 reflections with I ~ 2a (I). The heterocyclic four-membered
ring has a puckering angle of 8.9(4) 0
• The dihedral angle between
the best planes of the /)-propiothiolactone and benzene rings is
84.1(2) 0
• The structure consists of discrete molecules connected
along the a axis by intermolecular hydrogen bonds N-H ... O of
291.9(7) pm.
