From an arene‐rich liquid clathrate medium the title compound can be isolated in crystalline form. It is the first example of a compound in which an ionophore is stabilized by NH 4 +– π interaction. The crystal contains a linear supramolecular complex comprising five components (see picture) in which the cryptate molecules are elongated along their long axes.
