The title hydrated mol-ecular organic salt, C10H10N2 (2+)·C10H6O6S2 (2-)·2H2O, crystallized with half a bipyridinium cation, half a naphthalene-2,6-di-sulfonate anion and a water mol-ecule in the asymmetric unit. The whole cation and anion are generated by inversion symmetry, the inversion centers being at the center of the bridging C-C bond of the cation, and at the center of the fused C-C bond of the naphthalene group of the anion. In the crystal, the anions and cations stack alternately along the a axis with π-π inter-actions [inter-centroid distance = 3.491 (1) Å]. The anions are linked via O-H⋯O(sulfonate) hydrogen bonds involving two inversion-related water mol-ecules, forming chains along [10-1]. These chains are bridged by bifurcated N-H⋯(O,O) hydrogen bonds, forming a three-dimensional framework structure. There are also C-H⋯O hydrogen bonds present, reinforcing the framework structure.
水合分子有机盐C₁₀H₁₀N₂(2+)·C₁₀H₆O₆S₂(2-)·2H₂O在不对称单元中结晶，含有半个联吡啶阳离子、半个萘-2,6-二磺酸盐阴离子和一个水分子。整个阳离子和阴离子通过反演对称性产生，反演中心分别位于阳离子桥连C-C键的中心以及阴离子萘基团稠合C-C键的中心。在晶体中，阴离子和阳离子沿a轴交替堆积，存在π-π相互作用[质心间距 = 3.491 (1) Å]。阴离子通过涉及两个反演相关水分子的O-H⋯O(磺酸盐)氢键相连，沿[10-1]形成链。这些链通过分叉的N-H⋯(O,O)氢键桥连，形成三维骨架结构。还存在C-H⋯O氢键，加强了骨架结构。
