Figure 7
A view of part of the crystal structure of (III)[link], showing the aggregation of three hydrogen-bonding motifs, viz. C(4), C21(4) and R33(10). Hydrogen bonds are drawn as dotted lines and C-bound H atoms have been omitted. Atoms marked with a hash (#) or an `at' symbol (@) are at the symmetry positions (x − 1, y, z) and (x − 2, y, z), respectively.
