The charged state of the 3d metal ions in layered cation-substituted disulfides CuCr1−x V x S2 was studied by X-ray photoelectron spectroscopy. An analysis of the energy positions and structure of the Cu2p 3/2 and Cr2p 3/2 X-ray photoelectron lines showed that the corresponding polycrystalline samples of CuCr1−x V x S2 contained mixed-valence chromium and copper ions. It was shown that the charged states of chromium and copper ions depended on the concentration of vanadium cations (x). The presence of mixed-valence Cu1+ and Cu2+ ions in CuCr1−x V x S2 may be correlated with the crystal structure of the corresponding layered disulfides.
