Binuclear iron(III) complexes Fe<SUB>2</SUB>(R-R′-sap)<SUB>2</SUB>(tcoq) have been prepared by the oxidation of binuclear iron(II) complexes Fe<SUB>2</SUB>(R-R′-sap)<SUB>2</SUB> with tetrachloro-<I>o</I>-benzoquinone (TCOQ), where H<SUB>2</SUB>(R-R′-sap) represents 2-(salicylideneamino) phenols with the substituent R on the salicylaldehyde ring and the R′ on the <I>o</I>-aminophenol ring. Magnetic measurements indicated the operation of an intramolecular antiferromagnetic spin-exchange interaction between the iron(III) ions, the exchange integrals being evaluated at −6–−10 cm<SUP>−1</SUP>. In both polarograms and cyclic voltammograms of these complexes, two redox processes attributable to Fe(III)–Fe(III)\rightleftharpoonsFe(III)–Fe(II)\rightleftharpoonsFe(II)–Fe(II) were observed.
