Figure 2
A perspective view of the second crystallographically independent molecule of (I), showing the atom-numbering scheme. Counter-ions have been omitted for clarity. Displacement ellipsoids are drawn at the 50% probability level. The suffix `A' denotes the symmetry operation (−x, −y + 2, −z + 1). H atoms are shown as small spheres of arbitrary radii. Intramolecular hydrogen bonds are shown as dashed lines. |
