چکیده مقاله
Abstract The complexes cis-[Fe(5,5′-dmbipy)2Cl2]X (X is Cl- in 1 and ClO4- in 2 and 5,5′-dmbipy is 5,5′-dimethyl-2,2′-bipyridine) were synthesized as precursors of new diiron complexes. The diiron complex [Fe(5,5′-dmbipy)(NCS)2(μ-OCH3)]2 (3) was obtained from the reaction of KSCN with 1 and 2. Complex 3 was obtained from the addition of KSCN to FeCl2·4H2O and then 5,5′-dmbipy. A new binuclear iron(III) complex [Fe(4bt)(NCS)2(μ-OCH3)]2 (4) (4bt is 4,4′-bithiazole) has also been synthesized from the reaction of [Fe(4bt)3](NO3)2 with KSCN in a mixture of methanol/acetonitrile solvent. All complexes were characterized by elemental analysis, IR, UV-Vis, and 1H NMR spectroscopy and their structures were studied by single-crystal X-ray crystallography. The 1H NMR and magnetic investigation show that both paramagnetic centers in 3 and 4 complexes are coupled by an antiferromagnetic interaction. The electrochemical behavior of complex 3 show FeII/FeIII and FeIII/FeIV redox couples, in which FeIII/FeIV show quasi-reversible redox behaviors in relatively low potential. © 2015 Elsevier B.V.
