A metal-organic framework functionalized with free carboxylic acid sites and its selective binding of a Cl(H2O)4(-) cluster.
A metal-organic framework with one-dimensional channels decorated with -COOH binding sites was synthesized under aqueous acidic conditions, which inhibited the participation of these groups to metal coordination or self-association by hydrogen bonding. This material selectively includes Cl(H2O)4- clusters in its channels, as revealed by single-crystal X-ray diffraction analysis, which represents the first structural characterization of such a water-chloride cluster.
