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.
