N2 - Materials exhibiting reversible hydrogen adsorption with high gravimetric and volumetric capacities are sought for use in on-board storage systems of hydrogen fuel cell-powered vehicles. Microporous metal-organic framework solids with high internal surface areas have been shown to display excellent storage properties, but only at cryogenic temperatures. Methods for synthesizing frameworks bearing coordinatively-unsaturated metal centers are therefore being developed as a means of increasing the H2 adsorption enthalpy. Reactions incorporating metal carbonyl units within Zn4O(1,4-benzenedicarboxylate)3 have been devised, and attempts at decarbonylating the resulting materials will be described. In addition, the use of pyrazole-, triazole-, and tetrazole-based ligands for generating frameworks with open metal coordination sites will be discussed, with emphasis on a sodalite-type framework exhibiting a high volumetric hydrogen storage capacity.
