5,5'-(Disulfanedi-yl)bis-(1-methyl-1H-tetra-zole).

In the title mol-ecule, C(4)H(6)N(8)S(2), two tetra-zole rings linked by a disulfide bridge form a dihedral angle of 71.32 (7)° [C-S-S-C torsion angle = -80.51 (10)°]. In the crystal, strong inter-molecular π-π inter-actions between the tetra-zole rings [centroid-centroid distance = 3.285 (3) Å] link pairs of mol-ecules into centrosymmetric dimers. Weak inter-molecular C-H⋯N hydrogen bonds further link these dimers, related by translation in the [100] direction, into columns.
