R factor = 0.018; wR factor = 0.041; data-to-parameter ratio = 18.7. The asymmetric unit of the title compound, C5H7N2 +.I3 consists of one 2-aminopyridin-1-ium cation (apyH+) and one triiodide anion, both located in general postions. The apyH+ cation is planar within the experimental uncertainties. The short N—C distance [1.328 (5) Å] of the exocyclic NH2 group is typical for the imino-form of protonated 2-aminopyridines. Consequently, the bond lengths within the six-membered ring vary significantly. The geometric parameters of the triiodide anion are in the typical range, with bond lengths of 2.8966 (3) and 2.9389 (3) A ̊ and a bond angle of 176.02 (1). In the crystal, N—H I hydrogen bonds connect adjacent ions into screwed chains a...
