Abstract

We report on a study of a ferric-wheel system by X-ray photoelectron spectroscopy. The sample investigated was a cyclic hexanuclear Fe(III) cluster entrapping an alkaline ion: [Li subset of Fe6L6]Cl, L=N(CH2CH2O)(3). The Fe3s and 2p photoelectron spectra recorded for the ferric wheel and other Fe compounds, where Fe hits the formal valence state 3+ or 2+, were compared. Uncommonly spectral features of the 3s line were qualitatively explained. Itseems that unlike the usual transition metal compounds the electron energyconfiguration in the cluster favors the population of a final state with high-spin arrangement of electrons and a ligand hole. This could be due to covalency in such molecular compounds. (C) 2001 Elsevier Science B.V. All rights reserved.
