Figure 2 A part of the crystal structure of (I). Three symmetry-related cations are represented, omitting H atoms not involved in the supramolecular network. Hydrogen bonds are represented by dashed lines, and weak contacts involving nitro groups have been omitted for clarity. Symmetry codes for cations: green x, y, z; gold − x, + y, − z; blue − x, − + y, − z. |
