Abstract

First-principles electronic structure calculations show that boron clusters $B_{98}$, $B_{99}$, $B_{100}$, $B_{101}$, and $B_{102}$ based on icosahedral-$B_{12}$ stuffed fullerenes are more stable than the fullerenelike boron clusters. These more stable structures are envisaged as an icosahedral $B_{12}$ each vertex of which is connected to the apex of a pentagonal pyramid $(B_6)$ via radial 2c-2e \sigma bonds. The resulting $B_{84}$ $(B_{12}@B_{12}@B_{60})$ retains the same symmetry as $C_{60}$, and the $B_n$ (n = 84–116) clusters are generated around it. We further project the possibility of producing such $B_{12}$ based giant clusters.
