AM1 (unrestricted Hartree-Fock) type semiempirical calculations have been carried out on (Li + nH(2))@C-60 systems having n=0-5. The results predict that these composite structures should be endothermic but stable systems. The Li atom interacts with pi-skeleton of the C-60 structure. The hydrogens inserted into Li@C-60 cage also undergo some interaction. (C) 2002 International Association for Hydrogen Energy. Published by Elsevier Science Ltd. All rights reserved.
