No way out : Small guest cations, such as [Et 4 N] + template the formation of stable and tightly closed octaanionic metallosupramolecular tetrahedra (see picture). Since [Et 3 NH] + is co‐encapsulated with exactly one water molecule, the filling of space seems to be a more pivotal factor for the templation than the symmetry of the cation. X‐ray crystallography excellently agrees with NMR spectroscopy and ESI‐FT‐ICR mass spectrometry data.
