Figure 2
(a) Two pairs of mol­ecules A and B forming a circular fragment through strong N—H⋯N hydrogen bonds (blue dashed lines), weak C—H⋯N hydrogen bonds (black dashed lines) and ππ stacking of triazole rings (contact between centroids (orange globes) shown as dashed orange line). (b) A supra­molecular chain composed of tetra­molecular units. Only ππ stacking is shown for clarity. (c) A projection of the supra­molecular chains along the b axis. The inter­molecular contacts are shown as black dashed lines. For clarity, the central chain is shown with a space-filling model, while the surrounding chains are shown in capped-stick mode and colored differently.
