Abstract

An aqua-bridged Mn metal–organic framework was prepared, and a dramatic structural transformation occurs upon solvent exchange–resolvation and desolvation–resolvation processes. The desolvated phase, formed by removing the aqua bridges, exhibits selective CO₂ uptake over N₂, H₂, and CH₄. Further, antiferromagnetic couplings are also found between Mn spins in the secondary building units.
