Figure 5
A packing diagram of (III), showing two tape structures (top and bottom) related by an inversion symmetry to each other, formed by O—H⋯N/O⋯·H—N and C—H⋯O hydrogen bonds (dashed lines). H atoms not involved in the hydrogen bonds are omitted for clarity. Symmetry codes: (i) x, y + 1, z; (ii) x, y − 1, z. |
