2,3-Diamino­pyridinium sorbate-sorbic acid (1/1)

M. Hemamalini, J. H. Goh and H.-K. Fun

Abstract: In the title mol­ecular salt-adduct, C5H8N3+·C6H7O2-·C6H8O2, the 2,3-diamino­pyridinium cation is essentially planar, with a maximum deviation of 0.013 (2) Å, and is protanated at its pyridine N atom. The sorbate anion and sorbic acid mol­ecules exist in extended conformations. In the crystal, 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 R12(6) ring motif. The carboxyl groups of the sorbic acid mol­ecules and the carboxyl­ate groups of the sorbate anions are connected via O-H...O hydrogen bonds. Furthermore, the ion pairs and neutral mol­ecules are connected via inter­molecular N-H...O hydrogen bonds, forming sheets lying parallel to (100).
