Figure 4
Packing diagram for B, showing C—H⋯O, C—H⋯F, C—H⋯π and π–π interactions [symmetry codes: (i) x, −y + $[{1\over 2}]$ , z − $[{1\over 2}]$ ; (ii) −x + 2, −y + 1, −z + 2; (iii) −x + 1, y − $[{1\over 2}]$ , −z + $[{3\over 2}]$ ; (iv) −x + 1, −y + 1, −z + 1]. Cg2 and Cg3 are the centroids of the C1–C6 and C10–C15 rings, respectively.
