Di-μ-hydroxido-bis-[aqua-(pyridine-2,6-dicarboxyl-ato)iron(III)] monohydrate.

In the dinuclear title complex, [Fe2(OH)2(C7H3NO4)2(H2O)2]·H2O, the two Fe atoms are separated by 3.063 (1) A. Inter­molecular O—H⋯O hydrogen bonds form an extensive three-dimensional hydrogen-bonding network, which consolidates the crystal packing.
