The reaction of the new dinucleating ligand susan(6-Me) with Fe(BF4)(2)6H(2)O results in formation of the homovalent (FeFeII)-Fe-II complex [(susan(6-Me)){Fe-II(-F)(2)Fe-II}](2+) and the mixed-valence (FeFeIII)-Fe-II complex [(susan(6-Me)){(FeF)-F-II(-F)(FeF)-F-III}](2+) depending on the absence or presence of dioxygen, respectively. Complex [(susan(6-Me)){(FeF)-F-II(-F)(FeF)-F-III}](2+) is the first molecular mixed-valence complex with a fluorido bridge. The short Fe-III-F bond of 1.87 a 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).
