Abstract
57Fe Mössbauer spectroscopy has revealed that carboxylato bridged binuclear iron complex, [FeII FeIII (bpmp) (ena) 2] (ClO4) 2, exhibits a mixed-valence state depending on temperature, where bpmp = 2, 6-bis[bis- (2-pyridylmethyl) -aminomethyl]-4-methylphenol and Hena = enanthic acid. Both of the polycrystalline sample and the film sample prepared by dispersing the complex in poly (methyl methacrylate) (PMMA) have been investigated. The rate of the intramolecular electron transfer between iron (II) and iron (III) ions for the polycrystalline sample abruptly increases above ca. 200 K, and that for the film sample is slightly increase in the temperature range of 80 K to 295 K. The results show that the intermolecular interactions affect the intramolecular electron transfer of the binuclear mixed-valence iron complex.
