Two dinuclear iron(III) compounds, [Fe2(HL1)2(L1)2] · MeOH (1) and [Fe2(μ- )3] (2) [L1 = N-(2-hydroxypropyl)(3-methoxysalicylaldimine) and = 1,2-bis(2-hydroxybenzylidene) hydrazine], have been synthesized and characterized. Structural analysis of 1 shows that the six-coordinate Fe(III)'s are linked by two alkoxo oxygen atoms from two Schiff-base ligands to form a rectangular arrangement of metal ions and oxygen atoms. The distance of these two Fe(III) ions is 3.2122(8) Å. In 2, three Schiff-base ligands coordinate two Fe(III) ions in a tetradentate mode; each iron is six coordinate with octahedral geometry. The Fe–Fe distance is 3.9304(10) Å. Magnetic susceptibility (2–300 K) indicates an antiferromagnetic interaction between the two oxygen-bridged Fe(III) ions with J = −13.6 cm−1 for 1.
