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

The mol­ecule of the title thia­diazole derivative, C(11)H(11)N(3)O(2)S(2), 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.
