In the title compound, C(15)H(10)ClNO(4)S, the heterocyclic thia-zine ring adopts a half-chair conformation with the S and N atoms displaced by 0.476 (5) and 0.227 (5) Å, respectively, on opposite sides of the mean plane formed by the remaining ring atoms. The structure is stabilized by inter-molecular N-H⋯O and C-H⋯O hydrogen bonds. In addition, intra-molecular O-H⋯O and C-H⋯N inter-actions ar...

In the title compound, C(9)H(7)NO(2)S(2), the benzine ring is essentially co-planar with the thia-zole ring, making a dihedral angle of 0.36 (7)°. In the crystal structure, mol-ecules are linked by inter-molecular O-H⋯N hydrogen bonds between the carb-oxy group and the thia-zole N atom into chains along [10]. The chains are assembled into a supermolecular layer structure by thia-zole ring S⋯S c...

The synthesis of novel acetal thia-cage compounds has been accomplished by the direct substitution for the oxygen atom by the sulfur atom in the reaction of the acetal groups of oxa-cages with Lawesson reagent (LR). Reaction of the tetraoxa-cage compound 2 with LR in dichloromethane at 25 degrees C sequentially gave the monothia-, dithia-, trithia-, and tetrathia-cage compounds 3, 6, 7, and 9. ...

In the title compound, [Fe(C5H5)(C32H23FN3OS)], both the thia-zolidine ring and the pyrrolidine ring adopt a twist conformation on the N-C(H) bridging bond. Their mean planes are inclined to one another by 10.05 (10)°, and they make dihedral angles of 82.09 (10) and 89.67 (11)°, respectively, with the cyclo-pentane ring. The F atom deviates by -0.0238 (2) Å from the benzene ring to which it is ...
