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

The crystal structure of the anhydrous form of the title dinuclear complex has been reported by Thich et al. (1976[Thich, J. A., Ou, C. C., Powers, D., Vasiliou, B., Mastropaolo, D., Potenza, J. A. & Schugar, H. J. (1976). J. Am. Chem. Soc. 98, 1425-1433. ]). For related structures, see: Aghabozorg et al. (2008[Aghabozorg, H., Manteghi, F. & Sheshmani, S. (2008). J. Iran. Chem.
