چکیده
The title salt, C3H6N3S2 (+)·Cl(-)·H2O, crystallized with two organic cations, two chloride anions and two water mol-ecules in the asymmetric unit. The methyl C atoms deviate from their respective bound ring planes by 0.081 and 0.002 Å. In the crystal, the components are connected via N-H⋯O, N-H⋯Cl and O-H⋯Cl hydrogen bonds, forming sheets lying parallel to (100). The sheets are linked into bilayers by O-H⋯Cl hydrogen bonds involving the chloride ions and water mol-ecules. Within the bilayers there are π-π inter-actions [inter-centroid distances = 3.4654 (4) and 3.4789 (4) Å] involving inversion-related cations.

In the title compound, C(5)H(7)N(3)OS(2), inversion dimers linked by pairs of N-H⋯N hydrogen bonds occur, forming R(2) (2)(8) ring motifs. These dimers are arranged into chains via inter-molecular C-H⋯O hydrogen bonds between the methylsulfanyl groups and the O atoms of the carbonyl groups. The acetamido-1,3,4-thio-diazole unit is essentially planar [r.m.s. deviation 0.045 (8) Å].

In the title compound, C(12)H(12)N(6)S(4), the two terminal thia-diazole rings are twisted with respect to the central benzene ring, making dihedral angles of 54.28 (4) and 76.56 (3)°. The dihedral angle between the two thia-diazole rings is 27.77 (4)°. Inter-molecular N-H⋯N hydrogen bonds stabilize the crystal packing, linking the mol-ecules into a tape along the b axis.
