First delocalization of a mono-fulvalene-bridged mixed-valence diiron complex on the infrared time scale

Abstract

Measurement of the infrared νCH(Cp) stretch around 800 cm–1 of the FeIIFeII(q= 2), FeII FeI(q= 1) and FeIFeI(q= 0) states of [Fe2Fv(C6Me6)2]q+(Fv= fulvalene) and FeIIFeII(q= 0), FeIIFeIII(q= 1) and FeIIIFeIII(q= 2) states of [Fe2Fv(C5Me5)2]q+ shows that FeIIFeI is delocalized whereas FeIIFeIII is localized; the electrochemical E° values indicate that the cyclopentadienyl permethylation increases the delocalization in the arene series whereas it decreases it in the C5Me5 one.
