JOURNAL OF MOLECULAR STRUCTURE-THEOCHEM, vol.680, pp.47-51, 2004 (SCI-Expanded)
Semiempirical quantum chemical calculations at the level of AMI (restricted Hartree-Fock) have been performed on a fullerene derivative, C54N4, theoretically obtained from C-60 and its mono and diprotonated forms. All these structures are stable, but endothermic in nature. Some calculated geometrical and physicochemical properties of these have also been reported. (C) 2004 Elsevier B.V. All rights reserved.
