title: N-(5-Sulfanyl-idene-4,5-dihydro-1,3,4-thia-diazol-2-yl)acetamide dimethyl sulfoxide disolvate.
abstract: In the title compound, C(4)H(5)N(3)OS(2)·2C(2)H(6)OS, the five-membered heterocyclic ring and the N-(C=O)-C plane of the acetamide group are essentially co-planar, with a dihedral angle of 1.25 (3)°. Inter-molecular N-H⋯O hydrogen bonds between the acetamide compound and the dimethyl sulfoxide mol-ecules stabilize the crystal structure. The two dimethyl sulfoxide mol-ecules are each disordered over two positions with occupancy ratios of 0.605 (2):0.395 (2) and 0.8629 (18):0.1371 (18).
