Figure 9
A packing diagram of (IV), showing the layer structure formed via the π–π interactions (magenta dashed lines), and the O—H⋯N/O⋯H—N and C—H⋯O hydrogen bonds (green dashed lines). Except for the methyl group, H atoms not involved in the hydrogen bonds are omitted for clarity. Cg1 is the centroid of the C1–C6 ring. [Symmetry codes: (iii) −x + 1, −y, −z + 1; (v) −x + 1, −y + 1, −z + 1.] |
