Abstract

The reactions of Zintl ions Sn9^4- formed in ethylenediamine solutions of K2Cs2Sn9 and Rb4Sn9 with elemental tellurium have been investigated. Addition of elemental tellurium to the filtrates of these solutions leads - depending on the reaction conditions - to four different products: Compounds K_0.36(1)Cs_3.64(1)[SnTe₄] (1) and Rb4[SnTe4] (2) contain the tetrahedral anion [SnTe4]^4-, and Cs₄[Sn₂Te₇] (3) features the anion [Te₂Sn(μ-Te)(μ-Te2)SnTe2]^4-, whereas a novel Zintl anion [Sn₄Te₁₂]^10- is present in compound K_0.44(i)Cs_9.56(1)[Sn₄Te₁₂] (4). Compounds 1, 2 and 4 have been structurally characterized by single-crystal X-ray diffraction.
