Abstract

The three-dimensional EHMO crystal orbital program has been used to study both quasi-one-dimensional neutral polymers (C 60) n and orthorhombic doped polymers (KC 60) n and (RbC 60) n . Our calculated results show that metallic conducting phases are formed in (KC 60) n and (RbC 60) n . The characteristics of the crystal orbitals near the Fermi level for all doped polymeric fullerenes are completely carbon like. These dopant K and Rb atoms are thoroughly ionized and the C 60 molecules form stable negative charge states with one additional electron in each C 60 molecule.
