Reactive gas pressure syntheses of nitride-diazenides and hydridometalates

Nitride-diazenides and hydridometalates (exemplified by the chemical systems Sr (Ba)-N-2 and Rb-Pt-H-2) are obtained by reactive gas pressure syntheses in autoclaves starting from the elements and binary precursors.. respectively. The formation of the nitride-diazenides can be described in terms of reversible redox-intercalation processes and that of the hydridometalates as reversible solid-gas redox reactions. Phase formation and stability regions of the intermediate compounds of the chemical systems under consideration are particularly controlled by the level of the applied gas pressure.
