Abstract:
The title compound, C4H4N6S5, consists of two 1,3,4-thia-diazol-2-amine moieties bridged by a tris-ulfanediyl group [S-S-S = 107.98 (6)°]. The conformation is supported by an intra-molecular π-π stacking inter-action. In the crystal, N-H⋯N hydrogen bonds link the mol-ecules, enclosing R 2 2(8) and R 5 5(31) ring motifs, into infinite channels/tubes propagating along the b-axis direction. Hirshfeld surface analysis revealed that the most important contributions for the crystal packing are from S⋯S (33.6%) and H⋯N/N⋯H (32.8%) inter-actions.
