Figure 6
The short contacts sorted by increasing value of δ parameter in the function of pressure. The dotted line divides polymorphs (I) and (IV). Analysis of ambient-condition structure was performed using previously reported data (CSD refcode: QQQAXG09; Patel et al., 2017). Where required, the positions of hydrogen atoms were normalized to C—H = 1.083 Å, N—H = 1.009 Å (Groom et al., 2016). |
