A remarkable selectivity on the basis of size is observed for the encapsulation of Et 4 N + in the presence of Me 4 N + and Pr 4 N + by a predesigned [Ga 4 L 6 ] 12− homochiral tetrahedral cluster (L=bis‐bidentate ligand). Immediate and quantitative stepwise replacement of R 4 N + counterions in the cluster cavity is observed by 1 H NMR spectroscopy (see below). The encapsulation of Et 4 N + is also observed in the solid state.
