Abstract: In the title compound, [Fe(C₁₂H₆N₂O₄)(H₂O)₄]·2H₂O, the Fe^II ion (site symmetry 2) is bonded to one N,N'-bidentate 2,2'-bipyridine-5,5'-dicarboxylate ligand and four water molecules, resulting in a distorted cis-FeN₂O₄ coordination geometry. A network of - interactions and O-HO hydrogen bonds gives rise to a robust supramolecular network in the crystal structure.
