[K+(2,2,2‐crypt)]2Ge92– containing the deltahedral Zintl anion Ge92– has been isolated from a solution of K4Ge9 in ethylenediamine in the presence of 2,2,2‐crypt, intended as an intermediate in mixed‐cluster synthesis. The subsequent crystallographic characterisation shows the closo‐Ge92– cluster unit to be tricapped trigonal‐prismatic with a symmetry very close to D3h. Each Ge92– unit is surrounded...
