摘要：

Six new derivatized deltahedral Zintl ions have been synthesized by reactions between the known Zintl ions Ge-9(n-) with the halides R3EX and/or the corresponding anions R3E- for E = Ge or Sn. This rational approach is based on our previous discovery that these derivatization reactions are based on nucleophilic addition to the clusters. All species were structurally characterized as their salts with potassium countercations sequestered in 2,2,2-crypt or [18]crown-6 ether. The tin-containing anions were characterized also in solutions by Sn-119 NMR spectroscopy. The reaction types for such substitutions and the structures of the new anions are discussed.
