1,2‐Bis(1,3‐dithio­lan‐2‐ylidene)hydrazine

The title molecule, C6H8N2S4, possesses a crystallographically imposed center of symmetry. The two five-membered rings are in half-chair conformations. The crystal packing is stabilized mainly by van der Waals forces.

Ethyl 3-oxo-1,2-benzisothiazoline-2-acetate 1,1-dioxide

In the title compound, C11H11NO5S, the saccharin and ethyl acetate moieties are nearly orthogonal. There are some weak intermolecular hydrogen-bond interactions which stabilize the crystal structure.

2-(1H-Benzo-1,2,3-triazol-1-yl)-4,4-di­methyl-3-oxo-N-phenyl­pentane­thio­amide monohydrate

The title compound, C19H22N4O2S·H2O, was synthesized in order to search for new benzotriazole compounds with high bioactivity. There are some intermolecular hydrogen-bond interactions in the crystal structure, providing stabilization.

4,4-Di­methyl-3-oxo-N-phenyl-2-(1H-1,2,4-triazol-1-yl)­pentane­thio­amide monohydrate

In the title compound, C15H18N4O2S, the dihedral angle between the planes of the phenyl and triazole rings is 69.47 (9)°. There are weak O—H⋯N, N—H⋯O and O—H⋯S intermolecular interactions in the crystal structure, contributing to its stability.
