Abstract

There was a problem with the @ sign in the original article (published 9 January 2001). The entire corrected article is republished here. This article should be cited as M. Waiblinger, K. Lips, W. Harneit, A. Weidinger, E. Dietel, and A. Hirsch, Phys. Rev. B 63, 045421 (2001); 64, 159901(E) (2001).

Nitrogen and phosphorus atoms enclosed in fullerenes keep their atomic ground-state configuration, and no charge transfer or covalent bonding to the cage occurs. These systems can be dissolved in organic solvents and reacted with addends without losing the atomic character of the guest atom. In this paper we present a detailed study of the annealing behavior of N@C60, N@C70, and P@C60, and of some N@C60 adducts. The disintegration of these systems, as recorded by electron paramagnetic resonance measurements, occurs in a temperature range between 400 and 600 K. The results are in qualitative agreement with potential-energy calculations, and confirm the proposed escape mechanism which proceeds via bond formation of the trapped atom with the cage. It is found that other combinations of group-V elements with fullerenes, e.g., N@C84, P@C70, and As@C60, are not stable at room temperature. The escape mechanism and the possibility of disabling this path are discussed.
