A unique supertetrahedral anion embedding a Cs⁺ cation is found in (C₄C₁C₁im)₇[Cs@Sn^II₄(Ge₄Se₁₀)₄], obtained upon ionothermal reaction of Cs₄[Ge₄Se₁₀]⋅H₂O and SnCl₄⋅5H₂O with [Pt@Bi₁₀][AlBr₄]₄ as reducing agent. The anion's topology is related to that of P2 supertetrahedral clusters, yet the T2‐type supertetrahedral [Ge₄Se₁₀] units are not linked via an inverse T2 unit, but via four Sn^II atoms. These allow for capturing of the Cs⁺ cation through their lone pairs. Quantum chemical studies show that the cavity in 1 is perfectly suited to accommodate a Cs⁺ ion. More information can be found in the Communication by S. Dehnen, et al. on page 11899.

封面人物：离子液体的多价14族硫族化物结构：0D ‐ {[Cs @ SnII4（GeIV4Se10）4] 7−}和2D ‐ {[SnII（GeIV4Se10）] 2−}（Chem。Eur。J. 46 / 2018）

在Cs ₄ [Ge ₄ Se ₁₀ ]的离子热反应中获得的（C ₄ C ₁ C ₁ im）₇ [Cs @ Sn ^II₄（Ge ₄ Se ₁₀）₄ ]中发现了一种独特的嵌入Cs ⁺阳离子的超四面体阴离子。 ⋅H ₂ O和的SnCl ₄ ⋅5H ₂ ö与[PT @毕₁₀ ] [AlBr ₄ ] ₄作为还原剂。阴离子的拓扑与P2超四面体簇的拓扑有关，而T2型超四面体[Ge ₄ Se₁₀ ]单元不是通过反T2单元链接的，而是通过四个Sn ^II原子链接的。这些允许通过它们的孤对捕获Cs ⁺阳离子。量子化学研究表明，在空腔1非常适合于容纳的CS ⁺离子。可以在S. Dehnen等人的《通讯》中找到更多信息。在第11899页。
