The title mol-ecule, C(6)H(4)N(2)S(4), has a crystallographically imposed centre of symmetry located at the mid-point of the N-N single bond. The mol-ecule is essentially planar: the two five-membered rings form a dihedral angle of 0.17 (6)°. The crystal packing exhibits short inter-molecular S⋯S contacts of 3.549 (2) Å.
