Figure 2 Hydrogen bonded supramolecular chains running parallel to the [010] direction of the unit cell. The N+—H⋯O− interactions composing the main spiral chain are represented by dashed pink lines and highlighted in yellow in the background. The N+—H⋯O− interactions located solely on the secondary spiral are represented as dashed green lines. For geometric details of the represented interactions see Table 2. Symmetry operations used to generate equivalent atoms: (i) − x, − + y, − z; (ii) − − x, + y, − z. |
