4-(4-Chloro­benzyl­ideneamino)-3-(1H-1,2,4-triazol-1-ylmeth­yl)-1H-1,2,4-triazole-5(4H)-thione

In the title compound, C12H10ClN7S, the dihedral angles made by the plane of the thione-substituted triazole ring with the planes of the other triazole ring and the benzene ring are 73.57 (3) and 46.65 (2)degrees, respectively. Inter-and intramolcular hydrogen bonds and pi-pi stacking interactions stabilize the structure.

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-Oxo-2-phenyl­ethyl morpholine-4-carbodi­thio­ate

The title compound, C13H15NO2S2, the morpholine ring adopts the usual chair conformation and the four C atoms deviate only slightly from coplanarity. The crystal structure is stabilized by some weak intramolecular C—H⋯S hydrogen-bond interactions.

4-[3-(1,2,4-Triazol-1-yl)propion­yl]phen­yl 4-fluoro­benzoate

In the title compound, C-18(14)3(3)H(FN)O, the dihedral angles made by the triazole ring with the plane of the central benzene ring and the p-fluorophenylcarbonyl group are 82.09 ( 2) and 82.05 (2), respectively. There are weak C-H...O intra- and intermolecular interactions in the crystal structure, which contribute to the stability.

(4-Fluoro­benzoyl)(1H-1,2,4-triazol-1-yl)­methyl morpholine-4-carbodi­thio­ate

In the title compound, C15H15FN4O2S2, the morpholine ring adopts a chair conformation. The dihedral angle between the benzene and triazole rings is 77.1 (7)°. There are some weak intermolecular and intramolecular interactions in the crystal structure, providing stabilization.
