Entropy directs the self-assembly of supramolecular palladium coordination macrocycles and cages.

ABSTRACT: The self-assembly of palladium-based cages is frequently rationalized via the cumulative enthalpy (ΔH) of bonds between coordination nodes (M, i.e., Pd) and ligand (L) components. This focus on enthalpic rationale limits the complete understanding of the Gibbs free energy (ΔG) for self-assembly, as entropic (ΔS) contributions are overlooked. Here, we present a study of the M₂ ^linL₃ intermediate species (M = dinitrato(N,N,N',N'-tetramethylethylenediamine)palladium(ii), ^linL = 4,4'-bipyridine), formed during the synthesis of triangle-shaped (M₃ ^linL₃) and square-shaped (M₄ ^linL₄) coordination macrocycles.
