Optimized geometries and total energies of a series of aza[60]fullerenes, C60-2nN2n, have been calculated by density functional theory using B3LYP/6-31G*. The minimum total energy of C58N2 is the isomer with a pair of N atoms sitting in the (1,4) positions of the [60]fullerene. Maximum relative stability in the series is obtained for the isomer of C48N12 with one N per pentagon and S6 point group symmetry. The nitrogen content in C48N12 is in close agreement with the observed nitrogen concentration in fullerene-like onions of CNx. C48N12 is iso-electronic with C60-12 and has an ionization potential which is 1.6 eV lower than that of C60. © 2001 Elsevier Science B.V.
