Abstract

The C-20 cage structure (X@C-20; X = Fe, Co, Ni) endohedrally doped with a metal atom has been investigated theoretically by performing molecular-mechanics optimizations, and semi-empirical PM3 level and density functional theory B3LYP/6-31G* level calculations within UHF formalism. Calculations have been performed with different spin configurations for the neutral systems.
