The M-X-M, a generalized form of metal-oxygen-metal (M-O-M) bridges, was proposed as a feature for strong CO2 adsorption from screening study with the classical force field approach. However, this feature was not considered essential for constructing MOFs specifically for selective CO2 capture, as many MOFs with M-O-M bridges interact strongly with both H2O and CO2. However, given that the overestimation of H2O interaction, which was observed in calculations using UFF and point charges, was corrected in this study, M-X-M still appeared in over 20 % of the promising MOFs often associated with high CO2 selectivity over H2O.
