(a) Powder x-ray diffraction pattern and Rietveld full-profile refinement of α-NaNH₂ structure at 0.05 GPa with λ = 0.3979 Å. The green vertical ticks indicate the expected Bragg positions and intensities of XRD peaks. (b) The crystal structures of α-NaNH₂. The yellow (largest), grey (medium), and pink (smallest) spheres represent sodium, nitrogen, and hydrogen atoms, respectively.
