Figure 2
Rietveld refinement of room-temperature X-ray powder diffraction data of BNN using the Ama2 structure and refining atomic xyz coordinates. The inset shows the pseudo-tetragonal 421 and 440 reflections, with the asterisks indicating some reflections characteristic for Ama2 relative to the other space groups investigated. Rwp = 5.94%, Rexp = 2.64%, GOF = 2.25. Note that the reflections marked with the two leftmost asterisks are composite reflections. |
