Ternary imides of Li–Mg and Li–Ca were synthesized and tested for hydrogen storage. Li 2 MgN 2 H 2 , as an example, reversibly stores 5.5 wt.‐% hydrogen at temperatures below 180 °C (see Figure) with relatively high desorption plateau pressures. The present work also reveals the significance of chemical reactions between amides and ionic hydrides in the design and synthesis of novel metal–N–H systems for hydrogen storage.
