Dinuclear cages are metallo‐supramolecular hosts assembled from a minimum of components. Numerous examples for the most trivial, lantern‐shaped topology (two metals bridged by three or four bowed ligands) have been reported, but other structural motifs are rare. In their Communication on page 22489, G. H. Clever and co‐workers detail a new variety for a [Pd 2 Ligand 4 ] assembly, consisting of two figure‐eight‐shaped chelate complexes, doubly connected by mechanical bonds. The chiral ligands are based on peptidic macrocycles, giving the nano‐sized object a natural‐product‐like character.
