2-Amino-4-methyl-pyridinium hexa-2,4-dienoate dihydrate.


ABSTRACT: In the title salt, C(6)H(9)N(2) (+)·C(6)H(7)O(2) (-)·2H(2)O, the non-H atoms of the 2-amino-4-methyl-pyridinium cation are coplanar, with a maximum deviation of 0.010 (1) Å. In the crystal structure, the pyridinium N atom and the 2-amino group of the cation are hydrogen bonded to the carboxyl-ate O atoms of the anion via a pair of N-H⋯O hydrogen bonds, forming an R(2) (2)(8) ring motif. The sorbate anions and water mol-ecules are linked through O-H⋯O hydrogen bonds, forming R(10) (10)(28) and R(6) (4)(12) ring motifs. The motifs form part of a three-dimensional framework.
