Özet

The title compound, C4H4N6S5, consists of two 1,3,4-thia­diazol-2-amine moieties bridged by a tris­ulfanediyl group [S—S—S = 107.98 (6)°]. The conformation is supported by an intra­molecular π–π stacking inter­action. In the crystal, N—H⋯N hydrogen bonds link the mol­ecules, enclosing R 22(8) and R 55(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%) inter­actions.
