Figure 3
A packing plot of I viewed down the b-axis direction showing how the 4-t-butyl phenyl groups interdigitate with c-glide related copies of themselves, leading to layers that extend parallel to the bc-plane centered on a = 0 (and 1), and stack along the a-axis direction. The strong hydrogen bonds between cation and anion (i.e., N1—H1N⋯O4) are shown as thick dashed lines. |
