T. Fujihara, A. Kobayashi and A. Nagasawa

Abstract: The title compound, 2C₈H₂₀N⁺·C₁₂H₆N₂O₄^2-·4H₂O, which is one of the precursors of the dye for DSC (dye-sensitized solar cells), consists of tetraethylammonium cations, 2,2'-bipyridine-4,4'-dicarboxylate anions and water molecules. The anion has a centre of symmetry and the pyridine ring is inclined to the carboxylate group by 7.9 (3)°. A two-dimensional network is formed through intermolecular O-HO hydrogen bonds between water molecules and the carboxylate groups of the anions.
