2-Methyl-5-[(3-methyl-4-nitrobenzyl)-sulfanyl]-1,3,4-thiadiazole

The molecule of the title thiadiazole derivative, C₁₁H ₁₁N₃O₂S₂, 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⋯π interactions and a short C⋯O contact [3.005 (7) Å] are present.
