Recent Developments in the Chemistry and Physics of Metal Fullerides

The current status of metal intercalation into fullerene hosts is reviewed. The extent to which widely accepted simple models of the metallic and superconducting behavior in the A 3 C 60 compounds are sustainable is examined. The search for higher superconducting transition temperatures is discussed in the context of the synthesis of fullerides with different anion charges, more complex structures, and derived from higher fullerene hosts.
