Abstract: The title complex, [Co(H₂O)₆](C₇H₆NO₃)₂·2H₂O, was synthesized by the reaction of Co(CH₃COO)₂·4H₂O and 4-oxo-4H-pyridine-1-acetic acid in an aqueous solution. The cobalt(II) ion, which lies on a center of symmetry, is coordinated by six water molecules to form an octahedron [Co-O = 2.077  (1)-2.084  (1)  Å]. A three-dimensional supramolecular framework is formed via O-HO hydrogen bonds between the anions and cations.
