Reported is the first rational synthesis of a trisubstituted deltahedral Zintl ion, [Ge9{Si(SiMe3)3}3]鈭?/sup> in this case, by the addition of the three substituents in a reaction of the parent naked deltahedral Zintl ion Ge94鈥?/sup> with {(Me3Si)3Si}Cl. The new species were crystallized and structurally characterized in [K(2,2,2-crypt)]2[Ge9{Si(SiMe3)3}3] (monoclinic, P21/c, a = 26.497(3) 脜, b = 24.090(2) 脜, c = 29.268(3) 脜, 尾 = 113.888(2)掳, V = 17082(3) 脜3, Z = 8, R1/wR2 = 0.0436/0.0812 for the observed data and 0.1023/0.1010 for all data).
