“…Additionally, the coordination chemistry of magnesium is less flexible than that of zinc, and octahedral complexes are often found. [6] In the case of polyfunctional ligands used for the synthesis of Mgbased MOFs, competitive coordination by water or other solvent ligands may result in low-dimensional network topologies or isolated complexes, and thus porosity cannot be expected. However, the first magnesium-based metal-organic framework with permanent porosity and accessibility for very small molecules (H 2 , O 2 ) was recently reported by Dinća and Long.…”
