The increase of the radius of the alkali cations from Li + to Cs + and the size of their coordination sphere determine the transition between supramolecular capsules to bowls, built by assembly of {Ni 6 } metallacycles. Noteworthy, the NR 4 + countercations linked to exo ‐binding sites becomes crucial to stabilize the multicomponent supramolecules. More information can be found in the Full Paper by A. Escuer et al. on page 11158.
