In the title compound, [Fe(C(12)H(10)N(2)O)(3)](ClO(4))(2), the metal center is coordinated by six N atoms from the three bidentate chelating ligands in a distorted octa-hedral coordination geometry, with overall formation of the meridional (OC-6-21) isomer. Inter-molecular O-H⋯O hydrogen bonds between the hydroxyl groups of the cation and the counter-anions form an infinite one-dimensional chain in the c-axis direction.
