Figure 2
A partial packing diagram for (I) ![[link]](../../../../../../logos/arrows/c_arr.gif) , showing two asymmetric units. For the sake of simplicity, only half of the unit cell along the c direction is shown; the other half of the cell is generated by the screw axis. The N—H⋯O hydrogen bonding within each of the four organic cations and that between molecules is shown by dashed lines. Thin solid lines show the intermolecular close contacts. The bands of O atoms (shown as full ellipsoids with shaded octants) are clearly seen, and repeat every quarter of the cell length along c. For clarity, all C-bound H atoms have been omitted. Displacement ellipsoids are drawn at the 40% probability level. |
