A unique supertetrahedral anion embedding a Cs + cation is found in (C 4 C 1 C 1 im) 7 [Cs@Sn II 4 (Ge 4 Se 10 ) 4 ], obtained upon ionothermal reaction of Cs 4 [Ge 4 Se 10 ]⋅H 2 O and SnCl 4 ⋅5H 2 O with [Pt@Bi 10 ][AlBr 4 ] 4 as reducing agent. The anion's topology is related to that of P2 supertetrahedral clusters, yet the T2‐type supertetrahedral [Ge 4 Se 10 ] 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.
