Figure 3
A packing diagram of (I), showing the column structure formed via the π–π interactions (magenta dashed lines). H atoms except for in the O—H⋯N/O⋯·H—N hydrogen bonds (green dashed lines) are omitted for clarity. Cg1, Cg2 and Cg3 are the centroids of the C1–C6, N2/C8–C11/C16 and C11–C16 rings, respectively. Symmetry codes: (iii) −x + 1, −y + 1, −z + 1; (iv) −x + 1, −y + 2, −z + 1. |
