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... interactions and a short C...O contact [3.005 (7) A ° ] are present.
