A highly porous agw-type metal–organic framework and its CO2 and H2 adsorption capacity

An unsymmetrical tricarboxylate ligand with linking alkyne moiety has been used to construct a highly porous metal–organic framework with agw topology. The obtained Cu(II) MOF exhibits a high BET surface area of 3337.0 m2 g−1, a large capacity of CO2 (21.2 mmol g−1 at 298 K and 20 bar) and a good H2 adsorption (5.8 wt% at 77 K and 20 bar).
