Figure 2 A view of the molecular packing in (I). All H atoms not involved in the short contact interactions have been omitted for clarity [symmetry codes: (i) 1 + x,y,z; (ii) 2-x, − + y, 3/2-z; (iii) 2-x, − + y, 3/2-z; (iv) 1-x, 1-y, 1-z] . The dotted lines indicate the C-H⋯O and C-H⋯π interactions. |
