Abstract

Abstract : Ternary transition metal amides were first synthesized by mechanochemical reaction without applying high temperatures, high pressures or long reaction times. Abstract : K2 [Mn(NH2 )4 ] and K2 [Zn(NH2 )4 ] were successfully synthesized via a mechanochemical method. The mixture of K2 [Mn(NH2 )4 ] and LiH showed excellent rehydrogenation properties. In fact, after dehydrogenation K2 [Mn(NH2 )4 ]-8LiH fully rehydrogenates within 60 seconds at ca. 230 °C and 5 MPa of H2 . This is one of the fastest rehydrogenation rates in amide–hydride systems known to date. This work also shows a strategy for the synthesis of transition metal nitrides by decomposition of the mixtures of M[M′(NH2 ) n ] (where M is an alkali or alkaline earth metal and M′ is a transition metal) and metal hydrides.
