Abstract

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.
