N2 - Rigid metal-organic frameworks have attracted considerable interest due to their high thermal stability and hydrogen storage ability. So far, a large number of carboxlyate-based frameworks have been produced, and some of them exhibit a high capacity for hydrogen uptake. Here, we present new pyrazolate-based metal-organic frameworks of CoII and ZnII, featuring a three-dimensional porous network structure composed of linked CoII chains. These new materials are highly thermally stable (up to 450 °C), and show high surface areas of ca. 2000 m2/g. Low-pressure H2 sorption analysis reveals unsaturated adsorption of up to 1.5 wt % of H2 gas at 77 K, and 1 atm. High-pressure H2 sorption data and magnetic studies will also be presented.
