Abstract: In the title compound, C₂₀H₂₁N₂⁺·C₇H₇O₄S^-·H₂O, the cation is nearly planar and exists in the E configuration. The cations and anions form individual chains along the b axis and are interconnected by weak C-HO interactions. The 4-methoxybenzensulfonate anions are linked to water molecules through O-HO hydrogen bonds, forming a three-dimensional network. The crystal structure is further stabilized by a C-H interaction involving the methoxyphenyl ring. The sulfonate anion is also involved in a weak intramolecular C-HO interaction which generates an S(5) ring motif.
