In the title compound, (C10H10NO)2[Ni(C7H3NO4)2]·CH3OH·H2O, the coordination geometry of the NiII atom can be described as distorted octahedral. In the crystal, noncovalent interactions play an important role in the stabilization of the structure, involving O—H⋯O, N—H⋯O and weak C—H⋯O hydrogen bonds and π–π stacking interactions between the pyridine rings of the pyridine-2,6-dicarboxylate ligands [centroid–centroid distance = 3.7138 (15) Å] and between the 8-hydroxy-2-methylquinolinium cations [centroid–centroid distances = 3.6737 (15), 3.4434 (14), 3.6743 (15), 3.7541 (16), 3.5020 (15) and 3.7947 (15) Å].
