Bis(μ-hydroxido-κ2O:O)bis[bis(5-carboxypyridine-2-carboxylato-κ2N,O2)iron(III)] dihydrate

Abstract

The complete binuclear complex in [Fe2(C7H4NO4)4(OH)2]·2H2O, is generated by the application twofold symmetry. The FeIIIatom 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 Fe...Fe separation within the dinuclear complex is 3.0657 (4) Å. In the crystal, O—H...O and C—H...O hydrogen-bonding interactions connect the molecules into a three-dimensional supramolecular network.
