Figure 2
The molecular packing and aryl–H⋯π(arene) interactions in (I). Note that there are three crystallographically distinct interactions which form tightly knit planar arrays of molecules normal to [010]. Only one of the two parallel planes that pass through the unit cell is shown. Cg1 and Cg2 represent the centroids of rings C10–C15 and C1–C4/C4a/C9a, respectively. [Symmetry codes: (i) 1 + x, ½ − y, ½ + z; (ii) x, ½ − y, z − ½; (iii) x − 1, y, z.] |
