In the crystal of the title compound, 2C(5)H(7)N(2) (+)·C(4)N(4)S(6) (2-)·H(2)O, inter-molecular 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 inter-actions 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 mol-ecules.
在标题化合物2C₅H₇N₂⁺·C₄N₄S₆²⁻·H₂O的晶体中，分子间的N—H⋯S和N—H⋯N氢键将四个阳离子和两个二阴离子连接成一个中心对称的簇。相邻簇的五元环和六元环之间的π-π相互作用[质心-质心距离 = 3.692 (3)、3.718 (3)、3.660 (3) 和3.696 (3) Å]以及涉及未配位水分子的O—H⋯N、O—H⋯S和N—H⋯O氢键进一步巩固了晶体堆积。
