Controlling the Size of Molecular Copper Clusters Supported by a Multinucleating Macrocycle.

ABSTRACT: The use of a nonrigid, pyridyldialdimine-derived macrocyclic ligand (³PDAI₂) enabled the synthesis of well-defined mono-, di-, tri-, and tetra-nuclear Cu(I) complexes in good yields through rational synthetic means. Starting from mono- and diargentous ³PDAI₂ complexes, transmetalation to Cu(I) proceeded smoothly with formation of AgX (X = Cl, I) salts to generate mono-, di-, and trinuclear copper complexes. Monodentate supporting ligands (MeCN, xylNC, PMe₃, PPh₃) were found to either transmetallate with or bind various di- and trinuclear clusters. The solution-phase dynamic behaviors of these species were studied through NMR spectroscopic investigations, and an in-depth study of the trinuclear systems revealed a rate depende
