title: KNH2-KH: a metal amide-hydride solid solution.
abstract: We report for the first time the formation of a metal amide-hydride solid solution. The dissolution of KH into KNH2leads to an anionic substitution, which decreases the interaction among NH2-ions. The rotational properties of the high temperature polymorphs of KNH2are thereby retained down to room temperature.
