Two 3D open coordination frameworks constructed by CdII or ZnII perchlorate and 4-(4-pyridyl)-3,5-bis(2-pyridyl)-1,2,4-triazole showing selective anion-exchange behaviors to acetate

This work presents two isostructural 3D CdII and ZnII coordination polymers consisting of open host coordination framework and perchlorate anionic guest, which show the selective anion-exchange behaviors toward acetate in an irreversible way.
