In the title compound, [NH(C2H5)3][Fe(C14H8N2O5)2]·H2O, the iron(III) ion is hexacoordinated by four O atoms in the basal plane [Fe—O distances in the range 1.904 (4)–1.909 (4) Å] and two N atoms in the axial plane [Fe—N = 1.981 (4) and 1.985 (4) Å] of two tridentate fully deprotonated 2-{[(2-oxido-5-nitrophenyl)methylene]amino}benzoato (H2L) ligands, forming a tetragonally elongated octahedral geometry. The triethylammonium cations and complex anions are linked by N—H...O hydrogen bonds into chains parallel to [100]. Disordered water molecules (occupancy ratio 0.6:0.4) occupy the voids in the crystal structure.
