Abstract: The reaction of a chalcone derivative and an arylmethylamine yields the title organic salt, C₈H₁₀NO₂⁺·C₁₆H₁₃O₅S^-·H₂O. The 1,3-dioxolane ring exhibits an envelope conformation. The C-C-C-C torsion angle of 16.7 (7)° between the 2-methoxy-5-vinylbenzenesulfonate unit and the phenyl ring indicates the non-planarity of the system. The polar heads of the anion and cation are connected by two bifurcated N-HO hydrogen bonds. The water molecule completes hydrophilic interactions by N-HO hydrogen bonds with the cation and O-HO bonds with the anion along the a axis.
