Abstract: The asymmetric unit of the title compound, C₁₀H₉N₂²⁺·2C₆H₄FN₂O₄^-·2H₂O, consists of one half of the (E)-4,4'-ethylenedipyridinium cation, one [(5-fluoro-2,4-dioxo-1,2,3,4-tetrahydropyrimidin-4-yl)acetamido]acetate anion and one water molecule, the complete formula unit being generated by a crystallographic inversion centre at the mid-point of the central C=C bond of the (E)-4,4'-ethylenedipyridinium cation. In the crystal structure, a three-dimensional network is formed via N-HO and O-HO hydrogen bonds.
