From the raction of sonochemically prepared GaI with LiEPh3 (E = Si, Ge) the compounds [Li(THF)2][GaI(EPh3)3] (E = Si: 22, E = Ge: 24), [Li(THF)4][GaI(SiPh3)3] (23), [Li(THF)4][Ga2(SiPh3)5] (21) and [Li(THF)4] [Ga3(GePh3)6] (25) as well as polymeric Li(THF)I (20) were obtained and structurally characterized. 21 is a monoanionic digallane, exhibiting a trigonal planar and a tetrahedrally coordinated gallium centre. 25 has a linear Ga3 core, where the terminal gallium atoms bear three GePh3-groups, each. The central Ga atom is only 2-coordinated. Thus, 25 may be a valuable hint to the formation of larger gallium clusters with naked gallium atoms. Derivatives of 21 and 25 have been studied by DFT methods. WILEY-VCH Verlag GmbH, 2001.
