Figure 9
Autostereographic (Katrusiak, 2001) projections of layers formed by the two shortest hydrogen bonds (per one –NH2 group) in 1,2-diaminoethane structures: (a) in phase Iβ at 1.1 GPa/296 K and (b) in phase III at 0.2 GPa/296 K. In addition to the two shortest NH⋯N bonds forming the layers, the NH⋯N bonds extending to neighbouring layers are also shown. The hydrogen bonds are indicated with red dashed lines. |
