Figure 8
Packing view of the hemihydrate structure showing the propagation directions of the hydrogen-bonded chains. In the lower half of the unit cell, chains propagate horizontally (right–left, along [110]; in the upper half they propagate longitudinally (forward–backward, along [10]). Hydrogen bonds are shown as turquoise dashed lines. Green dashed lines connect the centroids of the bromoquinoline substituents [3.432 (14) Å]. Partially occupied water molecules shown as spheres of arbitrary radius. For all other atoms, probability ellipsoids are at the 50% level. C-bound H atoms and labels for C H atoms are omitted for clarity. |
