“…In particular, the topological structure of a family of flat tened polyhedral carbon clusters C n (n = 72-96) was simulated. 108 The electronic structure of all the clusters considered was studied in the π electron approximation. The geometries of the (D 6h ) C 96 and (D 6d ) C 96 clusters were calculated by the MNDO, AM1, and PM3 semi empirical quantum chemical methods.…”
