The alkali metal amidozincates Li 4 [Zn(NH 2 ) 4 ](NH 2 ) 2 and K 2 [Zn(NH 2 ) 4 ] were, to the best of our knowledge, studied for the first time as hydrogen storage media. Compared with the LiNH 2 –2 LiH system, both Li 4 [Zn(NH 2 ) 4 ](NH 2 ) 2 –12 LiH and K 2 [Zn(NH 2 ) 4 ]–8 LiH systems showed improved rehydrogenation performance, especially K 2 [Zn(NH 2 ) 4 ]–8 LiH, which can be fully hydrogenated within 30 s at approximately 230 °C. The absorption properties are stable upon cycling. This work shows that ternary amides containing transition metals have great potential as hydrogen storage materials.
