X.-H. Li, X.-X. Lei and S. Wang

Abstract: The asymmetric unit of the title compound, C₁₀H₁₀N₂²⁺·2C₉H₅O₆^-·C₉H₆O₆·6H₂O, consists of half of a bipyridinium cation, one singly deprotonated 3,5-dicarboxybenzoate anion, one half of a benzene-1,3,5-tricarboxylic acid molecule and three water molecules that are linked by hydrogen bonds into a network structure. The two halves of the bipyridinium cation are related by an inversion centre and those of the benzene-1,3,5-tricarboxylic acid molecule by twofold rotation.
