| Sumario: | The asymmetric unit of the title compound, C(6)H(9)N(2) (+)·C(6)H(4)NO(2) (−)·0.63H(2)O, contains two crystallographically independent 2-amino-5-methylpyridinium cations, a pair of picolinate anions and two water molecules, one with an occupancy of 0.25. Both the 2-amino-5-methylpyridine molecules are protonated at the pyridine N atoms. In the crystal structure, the cations, anions and water molecules are linked via N—H⋯O, N—H⋯N and O—H⋯O hydrogen bonds, as well as by C—H⋯O contacts, forming a chain along the b axis. In addition, weak π–π interactions are observed between pyridinium rings, with centroid–centroid distances of 3.5306 (13) Å. |
