Abstract
The dimerization of a lantern-shaped Pd2L4 coordination cage yields two Pd4L8 catenanes with distinct topologies: a “classic” quadruply interlocked D4-symmetric structure and a newly discovered triply linked motif with C2h symmetry. The latter is stabilized by extensive non-covalent interligand contacts, opening a strategy to control the degree of mechanical interlocking, tuned by temperature and anion exchange, as reported by Guido H. Clever et al. in their Communication (e202423810).
