Ce@C{sub 82} has been isolated with a purity of nearly 99.5% by an efficient solvent extraction procedure, followed by HPLC separation. The UV-vis-near-IR absorption spectrum of the metallofullerene was measured at a wavelength range from 300 to 2100 nm. X-ray photoelectron spectroscopy (XPS) of Ce@C{sub 82} has been studied. The results suggest that, analogous to the La in La@C{sub 82}, the Ce in Ce@C{sub 82} donates three valence electrons to the carbon cage as opposed to two electrons suggested by a recent ab initio calculation. 15 refs., 2 figs.
