Russian-Doll-Type Metal Carbide Endofullerene: Synthesis, Isolation, and Characterization of Sc₄C₂@C₈₀

Abstract

For the first time, we have produced the stable compound Sc(4)C(2)@C(80)-I(h) and characterized it as a metal carbide endofullerene by FTIR and Raman spectroscopies in combination with DFT calculations. Furthermore, DFT calculations have demonstrated that this molecule has a Russian-doll-type structure, C(2)@Sc(4)@C(80).
