Figure 7
A partial packing diagram for (I), showing the centrosymmeric C—H⋯O hydrogen-bond dimer formation and the propagation of these dimers into a one-dimensional ribbon along the a axis through C—H⋯π interactions. Intermolecular interactions are shown as dashed lines and H atoms not involved in these interactions have been omitted for clarity. Ring centroids are indicated with solid circles. [Symmetry codes: (i) −x + 2, −y + 2, −z + 1; (ii) −x + 1, −y + 2, −z + 1; (iii) x + 1, y, z.] |
