It contains 7.66% by weight of hydrogen and has been studied as a potential hydrogen storage medium.〔Catalytic Synthesis of Organolithium and Organomagnesium Compounds and of Lithium and Magnesium Hydrides - Applications in Organic Synthesis and Hydrogen Storage, Bogdanovic B., Angewandte Chemie International Edition in English, 24, 4, 262–73, 〕 == Preparation == In 1951 preparation from the elements was first reported involving direct hydrogenation of Mg metal at high pressure and temperature (200 atmospheres, 500 °C) with MgI2 catalyst: :Mg + H2 → MgH2 Lower temperature production from Mg and H2 using nano crystalline Mg produced in ball mills has been investigated.〔Nanocrystalline magnesium for hydrogen storage, A Zaluska, L Zaluski, JO Ström–Olsen, Journal of Alloys and Compounds, 288, 1-2, 1999, 217-225, 〕 Other preparations include: * the hydrogenation of magnesium anthracene under mild conditions:〔Catalytic Synthesis of Magnesium Hydride under Mild Conditions, Bogdanovic B., Liao S-T, Schwickardi M, Sikorsky P., Spliethoff B., Angewandte Chemie International Edition in English, 19,(1980), 10, 818 – 819, 〕 :Mg(anthracene) + H2 → MgH2 * the reaction of diethylmagnesium with lithium aluminium hydride〔The Preparation of the Hydrides of Zinc, Cadmium, Beryllium, Magnesium and Lithium by the Use of Lithium Aluminum Hydride, Barbaras G.D., Dillard C., Finholt A.
