In the title compound, C7H8N6O2S, the dihedral angle between the imidazole and thiadiazole rings is 70.86 (15)°. In the crystal, molecules are linked into [10-1] chains by N-HN hydrogen bonds, which incorporate centrosymmetric R22(8) and R22(18) loops. The chains are linked by C-HO and C-HN interactions, generating a three-dimensional network. Very weak - stacking [centroid-centroid distance = 3.901 (17) Å] is also observed.
