Highly selective CO 2 sorption and inverse CO 2 /C 2 H 2 sorption selectivity (4.8 at 278 K, 100 kPa) were achieved with an organic–inorganic ionic crystal. The key for the high affinity toward CO 2 is the combination of structural flexibility and strong binding sites (K + ) characteristic of organic–inorganic ionic crystals.
