Extended Data Figure 6

a, High-pressure excess CO2 adsorption isotherm at 25 °C for mmen-Ni2(dobpdc) indicates that Langmuir-type adsorption behaviour is maintained even at high pressures. b, Isothermal adsorption measurements of water onto a sample of mmen-Mg2(dobpdc) at 40, 75 and 100 °C. c, Four isothermal adsorption measurements of CO2 at 75 °C onto a sample of mmen-Mg2(dobpdc) before exposure to water and after water isotherms at 40, 75 and 100 °C. No changes in the CO2 adsorption isotherms were apparent from exposure of the sample to water.
