Positive Cooperativity Induced by Interstrand Interactions in Silver(I) Complexes with α,α'-Diimine Ligands.

ABSTRACT: The allosteric positive cooperativity accompanying the formation of compact [Cu^I (α,α'-diimine)₂ ]⁺ building blocks contributed to the historically efficient synthesis of metal-containing catenates and knotted assemblies. However, its limited magnitude can easily be overcome by the negative chelate cooperativity that controls the overall formation of related polymetallic multistranded helicates and grids. Despite the more abundant use of analogous dioxygen-resistant [Ag^I (α,α'-diimine)₂ ]⁺ units in modern entangled metallo-supramolecular assemblies, a related thermodynamic justification was absent. Solid-state structural characterizations show the successive formation of [Ag^I (α,α'-diimine)(CH₃ CN)][X]
