Ion-Selective Assembly of Supertetrahedral Selenido Germanate Clusters for Alkali Metal Ion Capture and Separation.

ABSTRACT: Supertetrahedral chalcogenido (semi)metalate cluster-based frameworks possess high selectivity for alkali metal cations, matching the specific charge density of their inner surfaces, which enables their use as ion-exchange materials. Aggregates of the supertetrahedral chalcogenido metalate cluster offer even new perspectives for metal ion capture and separation. Herein, we report on ionothermal preparation of two corresponding model compounds, (C₂C₁Im)₇[Cs@Ge^II₄(Ge^IV₄Se₁₀)₄] (1) and (C₂C₁Im)₁₀[Na₅(CN)₆@Cu₆(Ge₄Se₁₀)₄(Cu)] (2). Their formation is reliant on one specific cation type e
