Figure 2
Part of a stack of molecules of (I), propagated in the b direction (left to right across the page). Non-H atoms are shown as 50% probability displacement ellipsoids and H atoms have been omitted for clarity; selected atoms are labelled. Dashed lines indicate two of the shorter contacts between ring centroids, which are themselves shown as small dots. [Symmetry codes: (i) x, y + 1, z; (ii) x, y − 1, z.] |
