Exchange Mechanisms in Ferrocinium Complexes

Abstract

Abstract We examine kinetic and potential exchange in 1:1 ion-radical complexes of ferrocene (Fc) and π-acceptors like tetracyanoethylene (TCNE). Spin-orbit and asymmetry split the (e2g)3 configuration of Fc+ and lead to anisotropic magnetic moments. The partly-filled Fc+ and TCNE− orbitals are almost orthogonal and suggest alternative charge-transfer processes involving the acceptor and ligands.
