Figure 8
A partial packing diagram of (III)

, showing the 2₁ helix running along the b-axis direction formed by O—H⋯O and N—H⋯O hydrogen bonds (black dashed lines). The C—H⋯O and π–π interactions observed in the chain are indicated by black and blue dashed lines, respectively. Cg1 and Cg3 are the centroids of the C1–C6 and C11–C16 rings, respectively. H atoms not involved in the hydrogen bonds have been omitted. [Symmetry codes: (i) −x + $[{1\over 2}]$ , y + $[{1\over 2}]$ , −z + $[{1\over 2}]$ ; (ii) x, y + 1, z.]
