Abstract The nominal composition of Yb₃C₆₀ compound is characterised by means of x-ray photoelectron spectroscopy. Evidence of the divalent state for the Yb cation in the as-grown crystalline Yb₃C₆₀ is obtained. After exposure to air the Yb₃C₆₀ compound transforms to an amorphous phase and Yb₂O₃ compound, while the valence state of the Yb cations changes from divalent to trivalent.
