Porous polymeric coordination compounds

A method for preparing a pillared porous polymeric coordination compound having the stiochiometric formula [Co3(bpdc)3(bpy)].4(DMF).(H2O), where (bpdc) is a biphenyl-4,4′-dicarboxylate polyfunctional ligand, bpy is a 4,4′-bipyridine exodentate ligand, and DMF is dimethylformamide, comprising contacting a polymeric precursor compound of the stiochiometric formula [Co(bpdc)(H2O)2].(H2O), where (bpdc) is a biphenyl-4,4′-dicarboxylate polyfunctional ligand, with bipyridine under solvothermal ligand-replacement conditions.

A process for the synthesis of a pillared porous polymeric coordination compound of the stiochiometric formula:

• [M3(pbd)3ed].x DMF.zH2O, where M is a transition metal selected from the group of transition metals having in at least one stable oxidation state classified as a Pearson soft or borderline acid, and which, in some oxidation state, can form stable bonds with ligands selected from the group consisting of ligands classified as Pearson hard bases and ligands classified as Pearson borderline bases, “pbd” is a polyfunctional ligand having at least two bidentate binding sites, “ed” is an exodentate ligand having at least two monodentate binding sites, and wherein “x” and “y” are selected independently to be any number of solvent molecules including zero, comprising contacting a compound of the stiochiometric formula [M(pbd)(H2O)2].(H2O) with an ed compound in the presence of dimethyl formamide under solvothermal ligand replacement conditions.
