Abstract

Density-functional theory calculations are presented for low-energy La@C72, La@C74 and La@C76 isomers with IPR (isolated pentagon rule) and non-IPR cages. The relative isomeric production yields at high temperatures are evaluated using the calculated terms, and the relationships to observations are discussed.
Keywords: metallofullerenes; DFT computations; isomeric stabilities; Gibbs-energy evaluations; IPR and non-IPR fullerene cages metallofullerenes; DFT computations; isomeric stabilities; Gibbs-energy evaluations; IPR and non-IPR fullerene cages
