英文摘要The interaction between KH and Mg(NH2)(2) is investigated. Results from temperature-programmed desorption measurements on samples of [Mg(NH2)(2)][KH]x (x=0.5, 1.0, and 2.0) indicated that dehydrogenation from [Mg(NH2)(2)][KH] occurred through a two-step reaction with an onset temperature as low as 60 degrees C. Accompanied by hydrogen release, K2Mg(NH2)(4) and MgNH successively developed at lower temperatures, whereas KMg(NH)(NH2) developed at higher temperatures. However, when dehydrogenation was conducted under isothermal and near-equilibrium conditions, a single-step reaction that led to the formation of KMg(NH)(NH2) was observed. KMg(NH)(NH2) is a new amideimide complex. The synthesis of KMg(NH)(NH2) can be achieved either by dehydrogenation of the [Mg(NH2)(2)][KH] mixture or by thermal decomposition of the [K2Mg(NH2)(4)][Mg(NH2)(2)] mixture.
