Amidoborane ammoniate formation is investigated by using isotopic labeling techniques. The formation of Ca(NH2BH3)2⋅2 NH3 is initiated by proton transfer from NH3BH3 to NH2− (amide), forming Ca(NH3)2+ and anionic [NH2BH3]− groups. The dehydrogenation of the ammoniate, which occurs at lower temperatures, is a result of the participation of NH3 in the dehydrogenation process via the combination of (NH3)Hδ+⋅⋅⋅Hδ−(NH2BH3−).
