The synthesis and characterization of the metalloid germanium clusters {Ge₉[Si(SiMe₃)₂(SiPh₃)]₂}^2– (1), {Ge₉[Si(SiMe₃)₃][Si(SiMe₃)₂(SiPh₃)]₂}^– (2), {Ge₉[Si(SiMe₃)₂(SiiPr₃)]₃}^– (3), and [Ge₉(SiHtBu₂)₃]^– (4), which were obtained by the reaction of the Zintl anion Ge₉^4– with different silyl halides, are presented. Compound 4 is the sterically least protected soluble Ge₉R₃^– cluster known to date, and thus has interesting structural features and may open the way to new coordination modes of metalloid Ge₉R₃^– clusters.
