In the title compound, C(17)H(11)FN(4)O(3)S(2), the five-membered thia-zolidinone and thia-diazole rings are almost planar, with r.m.s. deviations of 0.017 and 0.0019 Å, respectively. The 4-fluoro-phenyl ring is almost perpendicular to the thia-diazole ring, making a dihedral angle of 89.5 (3)°. The 4-nitro-phenyl ring is nearly coplanar with the thia-diazole ring, the dihedral angle being 7.9 ...

In the title compound, C19H14FNS2, the seven-membered thia-zepine ring adopts a slightly distorted twist boat conformation. The dihedral angle between the benzene rings is 53.6 (1)°. The mean plane of the thia-zepine ring is twisted by 34.3 (7)° and 36.6 (7)° from the benezene rings. A C-H⋯F interaction generates stacking of molecules along the ab plane.

In the title compound, C(15)H(14)Cl(2)N(2)OS, the piperidine ring adopts a chair conformation. The dihedral angle between the thia-zolidine ring and the dichloro-benzene ring is 9.30 (4)°; this near coplanar conformation is stabilized by the formation of an intra-molecular C-H⋯S hydrogen bond, which generates an S(6) ring. In the crystal, mol-ecules are linked by C-H⋯O hydrogen bonds, forming [...
