Abstract: The title complex, [Ni(H₂O)₆](C₇H₆NO₃)₂·2H₂O, was synthesized by the reaction of Ni(CH₃COO)₂·4H₂O and (4-oxo-4H-pyrindin-1-yl)acetic acid in an aqueous solution. The nickel^II ion, which lies on a center of symmetry, is coordinated by six water molecules to form an octahedron [Ni-O = 2.047  (1)-2.057  (1)  Å]. A three-dimensional supramolecular framework is formed via hydrogen bonds between the anions and cations.
