Kondo coupling of f and conduction electrons is a common feature of f-electron intermetallics. Similar effects should occur in carbon ring systems (metallocenes). Evidence for Kondo coupling in Ce(C{sub 8}H{sub 8}){sub 2} (cerocene) and the ytterbocene Cp*{sub 2}Yb(bipy) is reported from magnetic susceptibility and L{sub III}-edge x-ray absorption spectroscopy. These well-defined systems provide a new way to study the Kondo effect on the nanoscale, should generate insight into the Anderson Lattice problem, and indicate the importance of this often-ignored contribution to bonding in organometallics.
