A semiempirical treatment at the level of AMI type calculations has been carried out for Si-60 structure and compared with C-60 It has been found that Si-60 is more endothermic and thus less stable. Moreover, silicon substitutional doping on the periphery of hexagonal rings is more destabilizing than the I:ase involving periphery of the pentagonal rings in the structure of C-60.
