Figure 2
A diagram with unit-cell axes, showing the internal hydrogen bonding (dashed line) and close contacts (thin solid lines) for (I). Displacement ellipsoids are drawn at the 30% probability level. For clarity, all C-bound H atoms have been omitted unless they are involved in the bonding. Symmetry-related molecules involved in the close contacts are shown with open bonds to simplify the drawing. The close contacts shown involve parts of five other separate asymmetric units, of which one contains both O3i and Cl4i. The [AuCl4]− anion of the main molecule and the non-H atoms participating in the hydrogen-bonding interactions are also labelled. [Symmetry codes: (i) x − 1, y, z; (ii) x − , − y, 2 − z; (iii) x, 1 + y, z; (iv) x − 1, 1 + y, z; (v) 3 − x, + y, − z.] |
