2-Amino-3,5-dichloropyridinium Chloride Monohydrate

The monohydrate hydrochloride salt of 2-amino-3,5-dichloropyridine, C₅H₅Cl₂N₂⁺.Cl^-.H₂O, was isolated from water by slow evaporation. The complex exhibits hydrogen bonds between the halide ions and both the pyridinium [3.109 (2) Å] and the amino [3.303 (2) Å] protons. Bond lengths and angles are comparable to those of previously studied pyridine complexes. The C-Cl bond lengths are 1.732 (2) and 1.721 (2) Å, and the C-NH₂ bond length is 1.328 (2) Å.
