Excerpt of the packing in the crystal structure of (a) 1a and (b) 1b viewed along the crystallographic b- and c-axis directions, respectively. In the latter case, the structure domains formed by crystallographically non-equivalent molecules I and II are highlighted by different colors. All hydrogen atoms are omitted for clarity. |
