摘要
Method for preparing an ammine metal borohydride of formula: AxM(BH4)x+m(NH3)n wherein: A is an alkali metal, M is a metal different from an alkali metal, 0 ≤ x ≤ 2, n > 0, and m > 0, the method comprising - a nucleophilic addition reaction, implemented in liquid ammonia NH3, of a metal hydride of formula AxMHx+m and a borane complex of formula L•BH3, L being a solvent forming a complex with a borane compound BH3, such as to obtain a metal borohydride complex of formula AxM(BH4)x+mLn, and - a displacement reaction between the metal borohydride complex and liquid ammonia to obtain the ammine metal borohydride.
