Abstract: The molecule of the title thiadiazole derivative, C11H11N3O2S2, has a butterfly-like structure and the whole molecule is disordered with a site-occupancy ratio of 0.629 (4):0.371 (4). The molecule is disordered in such a way that the 3-methyl-4-nitrophenyl units of the major and minor components are approximately related by 180° rotation around the C-N bond axis. The dihedral angle between the 1,3,4-thiadiazole and benzene rings is 70.8 (4)° in the major component and 74.9 (6)° in the minor component. In the crystal, molecules are arranged into screw chains along the c axis. These chains are stacked along the b axis. Weak intermolecular C-H...O and C-H...[pi] interactions and a short C...O contact [3.005 (7) Å] are present.
