A Robust Heterometallic Pt₂Pd₂L₈ Double Cage Catenane.

ABSTRACT: The combination of different metal ions in supramolecular structures can lead to the emergence of new features, such as enhanced stability, reduced symmetry, and peculiar reactivity. Mechanically interlocked architectures containing dissimilar metal ions are still scarce. Herein, we report the first example of a heterometallic, quadruply interlocked Pt₂Pd₂L₈ cage catenane, assembled via a combination of metal-mediated self-assembly and dynamic covalent chemistry. While direct complexation of the used asymmetric ligand with a mixture of Pt(II) and Pd(II) ions could yield 14 different monomeric and 576 interlocked cage products, the chosen approach allowed us to selectively obtain one PtPdL₄ monomeric cage and a single Pt₂Pd₂L
