2,3-Diamino-pyridinium (2E,4E)-hexa-2,4-dienoate

, : 2,3-Diamino-pyridinium (2E,4E)-hexa-2,4-dienoate. Acta Crystallographica. Section E, Structure Reports Online 66(Pt 9): O2369-O2369

In the title salt, C(5)H(8)N(3) (+)·C(6)H(7)O(2) (-), the pyridine N atom of the 2,3-diamino-pyridine mol-ecule is protonated. The 2,3-diamino-pyridinium cation is essentially planar, with a maximum deviation of 0.068 (2) Å for one of the amino N atoms. The sorbate anion adopts an extended conformation. In the crystal structure, the protonated N atom and one of the two amino-group H atoms are hydrogen bonded to the sorbate anion through a pair of N-H⋯O hydrogen bonds, forming an R(2) (2)(8) ring motif. The ion pairs are further connected via inter-molecular N-H⋯O and C-H⋯O hydrogen bonds, forming two-dimensional networks parallel to (100).
