Mineralomimetic Sodalite- and Muscovite-Type Coordination Frameworks. Dynamic Crystal-to-Crystal Interconversion Processes Sensitive to Ion Pair Recognition

Abstract
A flexible sodalite-type metal organic framework [Cu(pyrimidine-2-olate)2]n (1R) is obtained in a self-assembly process involving Cu2+ ions and pyrimidine-2-olate ligands. 1R suffers a series of sequential and reversible structural changes upon solid-liquid sorption processes of metal nitrates. The 1C-to-1O transformation occurs only with large cations.
