Abstract: The chemical structural unit of the title compound [systematic name: bis(4,4'-bipyridin-1-ium) bis(5-fluoro-1,2,3,6-tetrahydro-2,6-dioxopyrimidine-3-acetate) monohydrate], 2C₁₀H₉N₂⁺·2C₆H₄FN₂O₄^-·H₂O, comprises two ion pairs and one water molecule, which lies on a twofold rotation axis. O-HO, N-HO and N-HN hydrogen-bond interactions connect the cations, anions and water molecules to produce a ribbon-like double-chain along the [101] direction. The hydrogen-bonding pattern can be described in graph-set notation as R₆⁸(24)C₂²(16).
