Supramolecular complex : We describe the synthesis and structural characterization of the unsymmetrical calix[4]‐bis‐crown and its heterodinuclear K + and Ag + complex as a first case (see figure): both metal ions are stabilized not only by donor–metal dative bonds but also cation–π interactions, which can be visualized in terms of a chopsticks‐type π‐coordination process.
