New record size! The reaction of Li[N(SiMe 3 ) 2 ] with a metastable solution of GaBr leads to good yields of [Ga 84 {N(SiMe 3 ) 2 } 20 ] 4− (see picture), the largest Group 13 metalloid cluster that has been structurally characterized to date. On the basis of its highly symmetrical structure elements with predominantly covalent bonds, it is classified between the metalloid Al 77 cluster and the fullerenes with respect to its bonding character.
