In the title compound, C15H10Cl2N4O2S, the three rings are nearly coplanar. In the crystal structure, intermolecular N—H
N, C—HCl and C—HN hydrogen-bond interactions are observed. Intermolecular π–π stacking interactions are also present.

In the title compound, C10H6F2N4O2S, the urea group is essentially coplanar with the thiadiazole ring and nearly perpendicular to the benzene ring. The face-to-face distance of 3.2225 (15) Å and the centroid separation of 3.5862 (17) Å between parallel thiadiazole rings indicate the existence of π–π stacking between neighbouring molecules. There are two molecules in the asymmetric unit.

In the title compound, C11H9N5O5S2·C3H7NO, the urea scaffold, which adopts a planar configuration mediated by intramolecular N—HO hydrogen bonds, is nearly coplanar with the thiadiazole ring and the benzene ring. Intermolecular paired N—HN hydrogen bonds result in the formation of an R22(6) motif. Intermolecular π–π stacking interactions are also present.
