Abstract
The title compound, C8H10N8S2·2C2H6SO, was obtained unintentionally during an attempt to prepare a thiol-ate derivative of trimethyl-tin. The complete disulfide mol-ecule is generated by twofold rotation symmetry and the C - S - S - C torsion angle around the S - S bond is -85.70 (10)°. The mol-ecules are connected via N - H⋯N hydrogen bonds into strongly corrugated layers parallel to (001), generating an R 2 2(8) motif. The solvent mol-ecule, which exhibits minor disorder of its S atom [site occupancies = 0.9591 (18) and 0.0409 (18)], is linked to this layer via a pair of N - H⋯O inter-actions.
