The electronic structure of free radicals and Cu(II) complexes with the nitronyl nitroxide radical and aminonitrone is studied by X-ray photoelectron spectroscopy (XPS). N1s XPS spectra of nitrogen atoms of Cu(II) complexes with aminonitrones confirm the diamagnetic nature of the ligands. The binding energies of the main peak and the intense satellite structure in the Cu2p (3/2,1/2) spectra of the complexes under study correspond to the Cu(II) state. The structure of the satellite in the Cu2p (3/2,1/2) spectrum depends on the environment of the metal ion.
