Morphological Control of Heteroleptic cis- and trans-Pd2L2L′2 Cages

Morphological Control of Heteroleptic cis- and trans-Pd2L2L′2 Cages
Witold M. Bloch, Guido H. Clever, Wolf Hiller, Julian J. Holstein
Integrative self-sorting of palladium(II) metal ions and banana-shaped ligands is driven by the interplay of complementary ligand geometries to form cis- or trans-[Pd2L2L′2] heteroleptic cage structures (1–3 in the picture). In their Communication (10.1002/anie.201702573), G. H. Clever and co-workers report a topologically unprecedented “doubly bridged figure eight” assembly in which one of the ligands is forced to adopt an anti-conformation. The extent of the geometric constraints in the heteroleptic cage system is further demonstrated through highly selective ligand-substitution reactions.
