title: A Mixed-Valence Fluorido-Bridged FeIIFeIIIComplex.
abstract: The reaction of the new dinucleating ligand susan6-Mewith Fe(BF4)2·6H2O results in formation of the homovalent FeIIFeIIcomplex [(susan6-Me){FeII(μ-F)2FeII}]2+and the mixed-valence FeIIFeIIIcomplex [(susan6-Me){FeIIF(μ-F)FeIIIF}]2+depending on the absence or presence of dioxygen, respectively. Complex [(susan6-Me){FeIIF(μ-F)FeIIIF}]2+is the first molecular mixed-valence complex with a fluorido bridge. The short FeIII-μ-F bond of 1.87 Å causes a large reorganization energy, resulting in a localized class II system with an intervalence charge-transfer band of high energy at 10000 cm-1.
