Bis(2-amino­pyridinium) 5,5′-disulfanediylbis(1,3,4-thia­diazole-2-thiol­ate) monohydrate

In the crystal of the title compound, 2C(5)H(7)N(2) (+)·C(4)N(4)S(6) (2−)·H(2)O, inter­molecular N—H⋯S and N—H⋯N hydrogen bonds link four cations and two dianions into a centrosymmetric cluster. The crystal packing is further consolidated by π–π inter­actions between the five- and six-membered rings of neighbouring clusters [centroid–centroid distances = 3.692 (3), 3.718 (3), 3.660 (3) and 3.696 (3) Å] and via O—H⋯N, O—H⋯S and N—H⋯O hydrogen bonds involving the uncoordinated water mol­ecules.
