Gas Adsorption in an Isostructural Series of Pillared Coordination Cages



Eric J. Gosselin, Gregory R. Lorzing, Benjamin Trump, Craig Brown, Eric D. Bloch


The synthesis and characterization of six novel pillared metal-organic polyhedra is reported. By utilizing dabco (1,4-diazabicyclo[2.2.2.]octane), a pillar with increased basicity as compared to typical pillars such as pyrazine, three new stable copper-based polyhedra were prepared. Extending this strategy to iron(II) afforded three isostructural iron polyhedron-based materials. Four of the solids reported here retain high porosity and crystallinity upon solvent evacuation. Importantly, the iron solids represent rare examples of iron paddlewheel-based metal-organic materials that are stable to solvent evacuation. Neutron powder diffraction studies on these materials indicate the triangular and square windows of the polyhedra are prime C2Hx adsorption sites.
