Zr IV Coordination Polymers Based on a Naturally Occurring Phenolic Derivative

The reactivity under solvothermal conditions of the Zr IV ion with the naturally occurring gallic acid ligand has been evaluated in depth. The study led to the isolation of four microcrystalline hydroxycarboxylate‐based coordination polymers (MIL‐151 to ‐154). Through the use of a combination of sol...

Description
Summary:The reactivity under solvothermal conditions of the Zr IV ion with the naturally occurring gallic acid ligand has been evaluated in depth. The study led to the isolation of four microcrystalline hydroxycarboxylate‐based coordination polymers (MIL‐151 to ‐154). Through the use of a combination of solid‐state NMR and high‐resolution X‐ray powder diffraction analyses, the structures of two of these phases (MIL‐153, MIL‐154) were solved. In both cases, the gallol motifs favour the formation of rod‐like inorganic units built up from ZrO 8 polyhedra. Although one compound (MIL‐151) was found to be microporous ( S BET ≈ 470 m 2  g –1 ), its poor crystallinity prevented comprehensive structural analysis. Nevertheless, a comparison of its physicochemical features with those of the fully characterized solids allows a plausible structural model to be proposed.
