Figure 5
The π–π stacking of (II)[link], augmented by C—H⋯O hydrogen bonds (dashed lines). Spheres represent ring centroids and centroid–centroid inter­actions are shown as dotted lines. H atoms not involved in hydrogen bonding have been omitted for clarity. [Symmetry codes: (i) x, −y + ½, z − ½; (ii) x, −y + ½, z + ½; (iii) x, y, z + 1; (iv) x, −y + ½, z + [3 \over 2].]
