Sažetak
Due to daily increase in energy demand it is a great task to explore and use a sustainable and carbon-free energy systems. Hydrogen, as clean and easily productive (from water and renewable energy) is possible future energy carrier. Problem of its safe and efficient storage can be solved by solid state storage-through chemical bonding in crystalline compounds or by physical adsorption in porous materials[1]. Metal-hydride organic frameworks (HOF) are a novel hybrid materials designed by combining molecular building blocks of light-weight complex hydrides with organic linkers developed for coordination frameworks. They will be based on crystal engineering principles of coordination frameworks and have new properties (guest-host interactions, dehydrogenation properties) defined by the nature of the unique complex-hydride ligands. HOFs present new type of frameworks due to coordination than usually available in coordination frameworks. Also, directional anionic ligands other than hydrides can be used. We used imidazoles or its derivatives because the metal-imidazolate-metal angle of 145° is very similar to metal- borohydride-metal angle observed in Mg(BH4)2[2]. We will present first results on mono- and bi-metallic mixed anion (borohydride and imidazolate) frameworks based on Zn2+ node and light alkali metal cations (Li+, Na+). For synthesis we used ball-milling procedure under inert atmosphere, solvent free and liquid- assisted grinding with different solvents (DMF, DMSO, THF, acetonitrile).
