Structural and electronic studies of metal carbide clusterfullerene Sc2C2@C_s-C_(72)

摘要

We present a metal carbide clusterfullerene Sc2C2@C_s(10528)-C_(72), whose structure has been baffling for many years. A motional endohedral Sc2C2 cluster, special molecule geometry and electronic structure were found in Sc2C2@C_s(10528)-C72. The paramagnetic Sc2C2@C_s-C_(72) anion radical was successfully prepared by a chemical reduction method and hyperfine couplings in the ESR spectrum were observed.
