Mechanochemical Synthesis of Novel Mg- and Ca- Containing Bimetallic Amidoboranes

Mechanochemistry can be very useful for synthesis of bimetallic amidoboranes - very prominent materials for hydrogen storage. By using the mechanical ball milling technique, solventless solid state reaction between ammonia borane (NH3BH3), alkali metal hydrides (NaH, LiH) and alkaline earth metal hydrides (CaH2 and MgH2) is absolutely possible [1, 2]. Exclusively hydrogen and bimetallic amidoboranes are obtained as final products. Here we report several examples of successful synthesis - Na2Mg(NH2BH3)4, Li2Mg(NH2BH3)4, Na2Ca(NH2BH3)4 and Li2Ca(NH2BH3)4 – all prepared and characterised by our group.
