Purer than the driven snow. Ce 2 @C 80 has been isolated with a purity of >99% by an efficient extraction procedure, followed by an HPLC separation. The X‐ray photoelectron spectrum of Ce 2 @C 80 suggests that both Ce atoms inside the cage occur as Ce 3+ , in agreement with the results of a recent ab initio calculation.
