Dynamic Equilibria in Solvent-Mediated Anion, Cation and Ligand Exchange in Transition-Metal Coordination Polymers: Solid-State Transfer or Recrystallisation?

All the parts to make a whole: All the components (anion, cation, ligand) in AgI-N-heterocyclic coordination polymers, can be exchanged on contact with a solution phase of a competing component. The degree of reversibility of these transformations is determined by the ratio of the solubility product constants for the starting and resultant complexes, confirming that a “solid-state exchange mechanism” is not necessarily relevant to these systems.
