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-HO 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). For related structures, see: Aghabozorg et al. (2008); Eshtiagh-Hosseini et al. (2010).
