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

In the title mol­ecular salt–adduct, C(5)H(8)N(3) (+)·C(6)H(7)O(2) (−)·C(6)H(8)O(2), 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 conformation...

description In the title mol­ecular salt–adduct, C(5)H(8)N(3) (+)·C(6)H(7)O(2) (−)·C(6)H(8)O(2), 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 R (1) (2)(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).
