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].

8-Hydroxy-2-methylquinoline (0.320 g, 2 mmol) in methanol (10 ml) and 2,6-pyridine dicarboxylic acid (0.170 g, 1 mmol) in methanol (10 ml) were mixed and stirred until a clear solution was obtained. A solution of Ni(NO3)2.6H2O (0.145 g, 0.5 mmol) in methanol (5 ml) was added to the mixture and stirred for 30 min. Crystals of the title compound suitable for X-ray analysis were obtained by slow evaporation after two weeks.
H atoms bonded to N atoms and methanol O atom were found in a difference Fourier map and refined isotropically, with a restraint of N4—H4 = 0.86 (3) Å. The water H atoms were found in a difference Fourier map and refined with distance restraints of O—H = 0.82 (2) and H···H = 1.7 (4) Å and with a fixed Uiso(H). H atoms bonded to C atoms and hydroxyl O atoms were positioned geometrically and refined as riding atoms, with C—H = 0.93 (aromatic) and 0.96 (methyl) and O—H = 0.82 Å and with Uiso(H) = 1.2(1.5 for methyl and hydroxyl)Ueq(C,O). The highest residual electron density was found at 0.83 Å from Ni1 atom and the deepest hole at 0.56 Å from O12 atom.

Recently, we have defined a plan to prepare water soluble proton transfer compounds as novel self-assembled systems that can function as suitable ligands in the synthesis of metal complexes. In this regard, we have reported cases in which proton transfers from pyridine-2,6-dicarboxylic acid (pydcH2) to different amine base ligands (Eshtiagh-Hosseini, Aghabozorg et al., 2010; Eshtiagh-Hosseini, Alfi et al., 2010; Eshtiagh-Hosseini, Yousefi et al., 2010). This research plan has resulted in the formation of some novel proton transfer compounds based on carboxylic acid derivatives. For more details and related literature see our review article (Aghabozorg et al., 2008).
We have recently reported an isostructural Cu(II) compound with formula (8hmqH)2[Cu(pydc)2].CH3OH.H2O (8hmq = 8-hydroxy-2-methylquinoline) (Aghabozorg et al., 2011) and a related Ni(II) compound (Pasdar et al., 2011). The molecular structure of the title compound is presented in Fig. 1. The NiII atom is six-coordinated by two pydc ligands. As it can be seen, atoms N1 and N2 of the two pydc ligands occupy the axial positions, while atoms O1, O3, O5, and O7 form the equatorial plane, with Ni—O distances ranging from 2.1247 (16) to 2.1449 (16) Å. The N1—Ni1—N2 angle [173.76 (7)°] deviates from linearity. Therefore, the geometry of the resulting NiN2O4 coordination can be described as distorted octahedral. In the crystal structure, non-covalent 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 pydc ligands [centroid–centroid distance = 3.7138 (15) Å] and between the 8hmqH cations [centroid–centroid distances = 3.6737 (15), 3.4434 (14), 3.6743 (15), 3.7541 (16), 3.5020 (15) and 3.7947 (15) Å].
