Incorporation of active metal sites in MOFs via in situ generated ligand deficient metal-linker complexes

Two novel 3D MOFs, namely MOF-647A and MOF-648 (previously unknown trinodal 4-connected net), comprised of Cu ions and pyrazole-3,5-dicarboxylate were synthesized and characterized. A strategy for incorporating open metal sites in MOFs was investigated by utilizing an in situ generated metallinker complex as a precursor to construct MOF-648.
