In the 3-hy­droxy­picolinate anion of the title salt, C6H9N2+·C6H4NO3, an intra­molecular O—H...O hydrogen bond with an S(6) graph-set motif is formed, so that the anion is essentially planar, with a dihedral angle of 9.55 (9)° between the pyridine ring and the carboxyl­ate group. In the crystal, the cations and anions are linked via N—H...O hydrogen bonds, forming a centrosymmetric 2 + 2 aggregate with R22(8) and R42(8) ring motifs. The crystal structure also features N—H...N and weak C—H...π inter­actions.

In the title salt, C6H9N2+·C7H5O3, the anion is essentially planar, with a dihedral angle of 2.72 (17)° between the benzene ring and the carboxyl­ate group. In the crystal, the anions are connected by O—H...O hydrogen bonds, forming a 41 helical chain along the c axis. The protonated N atom and the 2-amino group of the cation are hydrogen bonded to the carboxyl­ate O atoms of the anion via a pair of N—H...O hydrogen bonds with an R22(8) ring motif. The ion pairs are further connected via another N—H...O hydrogen bond, resulting in a three-dimensional network.
