Figure 2
A view of the packing of (I), showing some of the hydrogen bonds, the π–π stacking interactions and the R55(10) synthon. For clarity, H atoms have been omitted. Thin dashed lines indicate hydrogen-bonding and π–π stacking interactions. CgAC and CgB are the centroids of the C1–C9/O7 ring system and the C10–C15 ring, respectively. [Symmetry code: (v) −x + 2, −y + 1, −z + 1; for (iii) and (iv), see Table 2.] |
