Figure 3 A packing diagram for (I), showing the C—H⋯π interactions. H atoms not involved in hydrogen bonding (dashed lines) have been omitted for clarity. [Symmetry codes; (i): 1 − x, + y, − z; (ii): 1 − x, − + y, − z]. (Cg1,Cg2 and Cg3, Cg4 are the centroids of the C1—C6, C9—C14; C1A—C6A, C9A—C14A rings, respectively). |
