The title compound, C 4 H 4 N 6 S 5 , 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 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%) interactions.
