We report an rht-type metal–organic framework (MOF) which exhibits a high adsorption capacity for C2 hydrocarbons and excellent selectivity over CH4. This MOF displays the highest reported C2H2–CH4 selectivity of 127.1 as well as a record high value for C2H4 adsorption enthalpy (49.5 kJ mol−1).

Organic Framework

The yttrium-based metal–organic framework, Y(btc) (btc = 1,3,5-benzenetricarboxylate), shows moderate uptake of methane (0.623 mmol g−1) and molecular oxygen (0.183 mmol g−1) at 1 bar and 308 K. Neutron powder-diffraction data for the guest-free, CD4-, and O2-loaded framework reveal multiple adsorption sites for each gas. Both molecular guests exhibit interactions with the host framework characterised by distances between the framework and guest atoms that range from 2.83 to 4.81 Å, with these distances identifying interaction most commonly between the guest molecule and the carboxylate functional groups of the benzenetricarboxylate bridging ligand of the host.
