Figure 3
A layer of ions in (I). Displacement ellipsoids are drawn at the 20% probability level. H atoms which participate in the formation of hydrogen bonds (dashed lines) are shown as small circles of arbitrary radii. For the purposes of this figure, the origin of the unit cell has been shifted to (, 0, 0). [Symmetry codes: (i) 1 + x, y, z; (ii) + x, − y, 2 − z; (iii) + x, − y, 2 − z.] |
