X-ray photoelectron spectra of the single valence platinum complexes K2[Pt(CN)4] · 3H2O(1),K2[Pt(CN)4]Cl0.3 · n H2O(2) and K2[Pt(CN)4]Cl2 · 3H2O(3) and the mixed valence compound [PtII(C2H5NH2)4]Cl4 · [PtIV (C2H5NH2)4Cl2] · 4H2O(4) have been measured. It is found that one can distinguish clearly between mixed and single valence compounds by electron spectroscopy. The Pt spectrum of (4) is a superposition of a PtII and PtIV spectrum. The chemical shift between (1) and (3) is normal, however (2) shows an anomalous low binding energy for the Pt 4f electrons. The importance of using reliable reference peaks for obtaining absolute binding energies is emphasized.
