Observation of an all-boron fullerene pp727 - 731 Hua-Jin Zhai, Ya-Fan Zhao, Wei-Li Li, Qiang Chen, Hui Bai et al. doi:10.1038/nchem.1999
Main-group analogues to fullerene-C60 have been predicted theoretically many times. Now, B40− has been observed using photoelectron spectroscopy and, with its neutral analogue, B40, confirmed computationally. In contrast to fullerene-C60, the all-boron fullerene (or borospherene) features triangles, hexagons and heptagons, bonded uniformly by delocalized σ and π bonds over the cage surface.
