Özet

The title hydrated molecular organic salt, C10H10N22+center dot-C10H6O6S22-center dot 2H(2)O, crystallized with half a bipyridinium cation, half a naphthalene-2,6-disulfonate anion and a water molecule 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 pi-pi interactions [intercentroid distance = 3.491 (1) angstrom]. The anions are linked via O-H center dot center dot center dot O(sulfonate) hydrogen bonds involving two inversion-related water molecules, forming chains along [101]. These chains are bridged by bifurcated N-H center dot center dot center dot(O, O) hydrogen bonds, forming a three-dimensional framework structure. There are also C-H center dot center dot center dot O hydrogen bonds present, reinforcing the framework structure.
