Figure 1 Molecular structure showing the labelling scheme and the inter- and intra-molecular hydrogen bonding. Hydrogen atoms have been omitted for clarity. The non-hydrogen atoms are represented by displacement ellipsoids at the 20% probability level. Symmetry transformations used to generate equivalent atoms: (i) x + 1, y, z; (ii) −x, y − , −z; (v) −x, y − , −z + 1; (vi) x − 1, y, z + 1. |
