High-energy photoelectron spectroscopy of some antimony compounds

Abstract

High-energy photoelectron (p.e.) spectra have been obtained for a number of compounds of antimony. The antimony 3d(,5//₂) binding energies range from 542.9, 533.3 eV for [Et₄N][SbF₆] to 538.6, 529.0 eV for Buⁿ₃Sb, but there is little correlation with the formal oxidation state. Assignment of the oxidation state of antimony on the basis of X-ray p.e. data alone is not possible with certainty and even gross structural differences may remain undetected by this method.
