Abstract

Recently it has been shown that buckminsterfullerene can be made to crystallize in a fee lattice when doped with various alkali metals eg. K, Rb, etc. Preliminary studies have shown the high propensity of C60 to be reduced without loss of stability. This may lead to interesting conductive pathways if a suitable dopant can be found which would act as an electronic “bridge” between adjacent “buckyballs” Out theoretical analyses have been geared towards a greater understanding of the reductive tendencies of C60, to discover how hypothetical metal-ion/C60, complexes differ from their corresponding simple, well characterized organometallic analogs. We demonstrate that the “metallocenium” link perturbs the electronic states of the C6 moiety including the frontier molecular Orbitals. Consequently, the metal ion plays an important role in establishing the electronic characteristics of metal-ion linked C60, chains and can be used to achieve desired properties.
