Figure 10
The pressure dependence of N⋯N distances in phases Iα, Iβ, Iγ (black circles) and III (green empty circles) at 296 K. Red points at 0.1 MPa refer to 274 K. For all plotted data, except one point in the structure at 1.5 GPa, the error bars are smaller than the size of the symbol. Close parallel lines have been used to indicate the presence of two identical N⋯N distances (see Table 3). |
