Synthesis, structures and hydrogen storage properties of two new H-enriched compounds: Mg(BH_4)_2(NH_3BH_3)_ 2 and Mg(BH_4)_2·(NH_3)_ 2(NH_3BH_3)

摘要

The synthesis, crystal structure and dehydrogenation performances of two new H-enriched compounds, Mg(BH_4)_2(NH_3BH _3)_2 and Mg(BH_4)_2·(NH _3)_2(NH_3BH_3), are reported. Due to the introduction of ammonia ligands, the Mg(BH_4)_2· (NH_3)_2(NH_3BH_3) exhibits dramatically improved dehydrogenation properties over its parent compound.
