The electrochemical behavior of a series of heterodimetallic 2-metalla-1,3-dichalcogena-[3]ferrocenophanes of general formula Cp∗(L)M[(EC5-H4)2Fe] (E = S, Se or Te; M = Rh, L = PMe3; M = Ir, L = PMe3, PPh3 or C≡NtBu) has been investigated. These complexes undergo two successive oxidation steps. In spite of the fact that both metal centres are potentially able to lose electrons, EPR spectra and theoretical considerations suggest that the bridging chalcogen atoms, which are centres of high electron density, also contribute significantly to the electron-removal processes.

Abstract
The electrochemical behavior of a series of heterodimetallic 2-metalla-1,3-dichalcogena-[3]ferrocenophanes of general formula Cp∗(L)M[(EC5-H4)2Fe] (E = S, Se or Te; M = Rh, L = PMe3; M = Ir, L = PMe3, PPh3 or C≡NtBu) has been investigated. These complexes undergo two successive oxidation steps. In spite of the fact that both metal centres are potentially able to lose electrons, EPR spectra and theoretical considerations suggest that the bridging chalcogen atoms, which are centres of high electron density, also contribute significantly to the electron-removal processes.File in questo prodotto:
