Synthesis, structures and dehydrogenation of magnesium borohydride–ethylenediamine composites

Magnesium Ethylenediamine Borohydride as Solid-State Electrolyte for Magnesium Batteries

“…The synthesis of Mg(en) 3 (BH 4 ) 2 was carried out according to a modified literature procedure19. Mg(BH 4 ) 2 was ball-milled with approximately 3.2 equivalents ethylenediamine (en) in a Spex 8000 shaker mill under argon atmosphere for 3 × 10 min, with 5 min break in between, using a balls-to-sample mass ratio of 10 to 1.…”

“…The synthesis, structure, and thermal stability of this compound have been reported recently19. In order to have good control over the stoichiometry, ca.…”

“…1b,c). We first discuss the coordination of Mg 2+ in Mg(en) 3 (BH 4 ) 2 for which a crystal structure model has been reported19. A conceptual sketch of the local coordination is shown in Fig.…”

Aluminum borohydride–ethylenediamine as a hydrogen storage candidate

“…[1][2][3][4][5][6][7][8][9][10][11][12] For the BNH compounds, the N-H mainly comes from ammonia, 2,11 amine, 4-6 and hydrazine, 7 and the B-H mainly comes from borane (BH 3 ), borohydrides (BH 4 À ) 8,9 or polyboranes (B 3 H 7 , B 4 H 10 ). One of the most popular systems comprises the BNH compounds, which can release hydrogen via the reaction of the N-H d+ /H dÀ -B dihydrogen bond and have achieved the most impressive dehydrogenation properties for hydrogen storage capacity, dehydrogenation temperature, kinetics and purity.…”

Aluminium complexes of B- and N-based hydrides: Synthesis, structures and hydrogen storage properties

“…The ligand may be chelating and/or bridging depending on the stoichiometry, like in C 2 H 8 N 2 complexes with Mg(BH 4 ) 2 [53]. A complex with low ligand-to-metal ratio, Al(BH 4 ) 3 $nC 2 H 8 N 2 (n ¼ 1/2), was observed in our most recent work [22], where C 2 H 8 N 2 was generated in low concentrations upon the decomposition of its borane complex:…”
