The complete binuclear complex in [Fe2(C7H4NO4)4(OH)2]·2H2O, is generated by the application twofold symmetry. The FeIII atom is coordinated by the O atoms of two bridging hydroxyl groups and by two N and two O atoms from two pyridine-2,5-dicarboxylato ligands, forming a distorted octahedral geometry. The FeFe separation within the dinuclear complex is 3.0657 (4) Å. In the crystal, O—HO and C—HO hydrogen-bonding interactions connect the molecules into a three-dimensional supramolecular network.
