A facile method for synthesizing crystalline lithiated amines by ball milling primary amines with LiH was developed. The lithiated amines exhibit an unprecedented endothermic dehydrogenation feature in the temperature range of 150–250 °C, which shows potential as a new type of hydrogen storage material. Structural analysis and mechanistic studies on lithiated ethylenediamine (Li 2 EDA) indicates that Li may mediate the dehydrogenation through an α,β‐LiH elimination mechanism, creating a more energy favorable pathway for the selective H 2 release.
