Fig. 1. (a) Coordination environment of Zn(ii) in 1cp. (b) Spacefilling view along [010] showing the twofold entanglement of 1cp and its lack of guest-accessible space. (c) Adsorption (filled symbols) and desorption (open symbols) isotherms for 1 recorded at 298 K with test gases CO2, CH4 and N2. (d) PXRD patterns of 1 under variable CO2 gas pressure at 298 K.
