Figure 4 A view in projection down the b axis of the crystal packing in (I). The layers shown in Fig. 3 are interspersed by the trifluoromethanesulfonate anions which are connected by N–H⋯O hydrogen bonds (orange dashed lines) to one layer, and C–H⋯O and C–H⋯F interactions (shown as purple and blue dashed lines, respectively) to the other. |
