Modulation of breathing behavior of layered coordination polymers via a solid solution approach: the influence of metal ions on sorption behavior

Abstract

Four iso-structural layered coordination polymers (CPs) of Cd(II) and Zn(II) were shown to exhibit breathing transitions with N₂/H₂ gases. Furthermore, the solid solutions containing Zn(II)/Cd(II) have shown better uptake capacities of gas than parent CPs. These results give some insights into the role of metal ions and anions for fine-tuning the porosity of CPs.
