Mechanochemistry is a very useful liquidless technique for synthesis of (bi)metallic amidoboranes [1-3]. Successful syntheses are obtained in solid state reactions of ammonia borane (borazane, NH3BH3) with alkali metal hydrides (NaH, LiH) and alkaline earth metal hydrides (CaH2 and MgH2), by using the PMMA and stainless steel (Fig. 1) milling jars. On such a way we synthesized two monometallic (NaNH2BH3, LiNH2BH3) and four bimetallic amidoboranes (Na2Mg(NH2BH3)4, Li2Mg(NH2BH3)4, Na2Ca(NH2BH3)4, Li2Ca(NH2BH3)4. Although all compounds show high gravimetric H2 storage capacity and low H2 desorption temperatures, their main problem still stays unsolved – rehydrogenation. Having that in mind there is one fundamental question – are (bi)metallic amidoboranes prominent materials for solid state hydrogen storage?
