The novel neutral and anionic gallium clusters Ga 10 R‘ 6 and [Ga 10 R* 6 ] - as well as [Ga 13 R* 6 ] - are obtained by reaction of “GaI”, prepared sonochemically from gallium and iodine, with Li(THF) 3 R‘ (R‘ = Si(SiMe 3 ) 3 = hypersilyl) and Na(THF) 2 R* (R* = Si t Bu 3 = supersilyl), respectively. Both of the Ga 10 clusters may be considered as conjuncto clusters consisting of two edge-sharing octahedrons. In Ga 10 R‘ 6, these contain a Ga 4 R‘ 4 and a Ga 2 R‘ 2 unit, and in [Ga 10 R* 6 ] -, they contain two Ga 3 R* 3 units. In addition to the syntheses and X-ray structure analyses of these three clusters, some hypersilylgallium halides are described, namely the [Li(THF) 2 ] + and [Li(THF) 3 ] + salts of [R‘GaI 3 ] - as well as the [Li(THF) 2 ] + salts of [R‘ 2 Ga 2 Br 4 ] 2 - and [R‘ 2 Ga 2 I 4 ] 2 - .
