The strength of interactions between CO2 and 23 building blocks of metal-organic frameworks (MOFs) are reported in this manuscript. This theoretical study is based on an incremental, explicitly-correlated coupled-cluster scheme with interference effects. This scheme allows the accurate calculation of molecular complexes such as zinc acetate (32 non-hydrogen atoms) at the CCSD(T) level close to the basis set limit. Higher CO2 affinity for complexes with nitrogen-containing heterocycles is predicted from the calculated interaction energies.
