Abstract: In the centrosymmetric title compound, [Zn₂(C₇H₃NO₄)₂(C₁₀H₈N₂)(H₂O)₆]·2H₂O, each Zn^II atom is six-coordinated in an octahedral geometry by one N atom of 4,4'-bipyridine (bpy), one N atom and one O atom of pyridine-2,4-dicarboxylate (pydc) and three water molecules. The crystal structure features O-HO hydrogen bonds between carboxylate groups and water molecules, and - stacking interactions between the bpy and pydc molecules.
