Stability of all molecular ions conceivable for C60 and C70

Abstract

Topological resonance energies (TREs) and bond resonance energies (BREs) were calculated for all conceivable molecular ions of C₆₀ (I_h) and C₇₀ (D_5h). On this basis these fullerenes were predicted to be thermodynamically and kinetically stable only when they carry total charges of 0 down to -12. This prediction is fully consistent with the chemistry of C₆₀ and C₇₀. Thus, the variation of the total charge markedly affects the stability of fullerenes.
