Multiarylpolycarboxylate-Mediated Hybrid Cobalt Phosphate Frameworks with Supramolecular Zeolitic Topology and Unusual I2O2 Connectivity

Two novel organic–inorganic hybrid frameworks containing multiarylpolycarboxylate linkers and cobalt phosphate layers, [H2DABCO]·[Co­(HPO4)­(bpdc)] (1) and [H2DABCO]3·[Co10(npa)3(PO4)6Cl2] (2), where bpdc = 4,4′-biphenyldicarboxylate, npa = 2,6-naphthalenedicarboxylate, and DABCO = 1,4-diazabicyclo[2.2.2]­octane, have been solvothermally synthesized. Compound 1 features a 3D zeolite-like supramolecular network with ABW topology, and compound 2 is a 3D framework structure with unusual I2O2 connectivity.
