Structural and electronic properties Of C@C-60 were studied via Hartree-Fock self-consistent field (SCF) and density functional B3LYP levels of theory with the STO-3G, 6-31G(d) and 6-31G(d, p) basis sets. Both singlet and triplet were considered. The triplet structure with C on the center of the C-60 cage was proved to be global minimum on the C@C-60 molecular potential energy surface. The calculated HOMO-LUMO gaps as well as the electron affinity (EA) and the ionization potential (IP) were also presented as an indicator of the kinetic stability. (C) 2004 Elsevier B.V.
