Dual structure evolution of a Ag(I) supramolecular framework triggered by anion-exchange: replacement of terminal ligand and switching of network interpenetration degree

A 3-fold interpenetrated Ag(I) coordination framework can exhibit dual structure evolution behaviours driven by distinct anion-exchange courses in which irreversible single-crystal to single-crystal transformation occurs, resulting in a switching of network interpenetration degree (from 3-fold to 2-fold).
