Abstract

We present a metal carbide clusterfullerene Sc₂C₂@C_s(10528)–C₇₂, 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–C₇₂ anion radical was successfully prepared by a chemical reduction method and hyperfine couplings in the ESR spectrum were observed.
