Bis{4-[(4-pyridyl)ethenyl]pyridinium} 4-sulfonatobenzoate trihydrate

L.-P. Zhang and L.-G. Zhu

Abstract: In the crystal structure of the title organic proton-transfer complex, 2C₁₂H₁₁N₂⁺·C₇H₄O₅S^2-·3H₂O, the cations form one-dimensional chains via intermolecular N-HN hydrogen bonds and these chains, in turn, form a two-dimensional network through - stacking interactions. In addition, the anions and water molecules are connected into a two-dimensional hydrogen-bonded network through intermolecular O-HO hydrogen bonds. The two motifs result in sheets of cations and anions stacked alternately.
