Sumario:The title compound, C(10)H(10)N(2) (2+)·C(8)Br(4)O(4) (2−)·2H(2)O, consists of a tetra­bromo­terephthalate dianion, a 4,4′-bipyridinium dication and two solvent water mol­ecules. Crystallographic inversion centers are situated at the center of the aromatic ring of the dianion as well as at the midpoint of the carbon–carbon bond connecting the pyridine rings in the dication. In the crystal, inter­molecular N—H⋯O hydrogen-bonding inter­actions between tetra­bromo­terephthalate dianions and protonated 4,4′-bipyridinium dications result in the formation of a chain-like structure. Further O—H⋯O hydrogen bonds between carboxyl­ate O atoms and water mol­ecules lead to the formation of a two-dimensional network in the crystal structure.
