XPS has been used to study the electronic structure of cobalt trimethylacetate complexes. The compounds were high-spin paramagnetic mono-and polynuclear Co(II) complexes, diamagnetic Co(III) complex and mixed polynuclear di-macroheterocyclic Co(II)/Co(III) one. The Co 2p(1/2)-Co 2p(3/2) spin-orbit splitting (Delta E-1) was close to 16, 15 and 15.3 eV, respectively. An intense satellite structure was most noticeable for the Co 2p and Co 3p lines in the case of paramagnetic compounds, but not for the diamagnetic complex. The XPS data are in good agreement with the X-ray structure analysis (XSA). (c) 2006 Elsevier B.V. All rights reserved.
