LiBF(4)‐Induced Rearrangement and Desymmetrization of a Palladium‐Ligand Assembly

Thirteen palladium‐ligand assemblies with different structures and topologies were investigated for the ability to bind lithium ions. In one case, the addition of LiBF(4) resulted in a profound structural rearrangement, converting a dincluclear [Pd(2)L(4)](4+) complex into a low‐symmetry [Pd(4)L(8)]...

Sumario:Thirteen palladium‐ligand assemblies with different structures and topologies were investigated for the ability to bind lithium ions. In one case, the addition of LiBF(4) resulted in a profound structural rearrangement, converting a dincluclear [Pd(2)L(4)](4+) complex into a low‐symmetry [Pd(4)L(8)](8+) assembly with two binding pockets for solvated LiBF(4) ion pairs. The rearrangement could only be induced by Li(+), indicating highly specific host–guest interactions. A structural analysis of the [Pd(4)L(8)](8+) receptor revealed a compact structure with multiple intramolecular interactions, reminiscent of what is seen for natural and synthetic foldamers.
