5,5′-[1,4-Phenylenebis(methylenesulfanediyl)]bis[1,3,4-thiadiazol-2(3H)-one] dimethyl sulfoxide disolvate
The asymmetric unit of the title compound, C12H10N4O2S4·2C2H6OS, contains one half of the p-xylene molecule and one dimethyl sulfoxide molecule. The p-xylene molecule is located about a crystallographic inversion centre. In the molecule, the thiadiazole and benzene rings are almost perpendicular to one another, with a dihedral angle of 88.95 (6)°. In the crystal, an N—H⋯O hydrogen bond is observed between the two components. The dimethyl sulfoxide molecule is disordered over two orientations with an occupancy ratio of 0.879 (1):0.121 (1)
5-({3-[(5-Amino-1,3,4-thiadiazol-2-yl)sulfanylmethyl]benzyl}sulfanyl)-1,3,4-thiadiazol-2-amine
In the title compound, C12H12N6S4, the two terminal thiadiazole 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 thiadiazole rings is 27.77 (4)°. Intermolecular N—H⋯N hydrogen bonds stabilize the crystal packing, linking the molecules into a tape along the b axis
N-(5-Ethoxy-1,3,4-thiadiazol-2-yl)benzamide
In the title compound, C11H11N3O2S, the dihedral angle between the thiadiazole and phenyl rings is 28.08 (7)°. In the crystal, molecules are linked into an inversion dimer by a pair of intermolecular N—H⋯N hydrogen bonds with an R

1-Benzoyl-2-thiobiuret
In the title compound [systematic name: N-(carbamoylcarbamothioyl)benzamide], C9H9N3O2S, the benzoyl and terminal urea fragments adopt cisoid and transoid conformations, respectively, with respect to the S atom. The benzoyl and thiobiuret groups are almost coplanar, making a dihedral angle of 8.48 (5)°. The molecular structure is stabilized by an intramolecular N—H⋯O hydrogen bond. In the crystal, N—H⋯O and N—H⋯S hydrogen bonds link the molecules into a sheet parallel to the bc plane
