Controlled Reducibility of a Metal–Organic Framework with Coordinatively Unsaturated Sites for Preferential Gas Sorption

Abstract

Gas grabber: Reduction of the porous metal–organic framework MIL-100(Fe) (see picture; X−: OH− or F−; red: O of trimesate ligands) to form coordinatively unsaturated sites at iron(II) (depicted as a violet circle) is essential for selective gas purification or the selective removal of unsaturated gas impurities.
