The title compound, (C(4)H(8)N(3)O)(H(3)O)[Co(C(7)H(3)NO(4))(2)]·3H(2)O, contains a protonated creatininium cation, a hydrox-onium (H(3)O)(+) cation, a Co(pydc)(2) (pydcH(2) = pyridine-2,6-dicarboxylic acid) complex anion, and three uncoordinated water mol-ecules. The Co(II) atom is coordinated by four O and two N atoms from two pydc ligands in a distorted octa-hedral environment. The structure also contains three uncoordinated water mol-ecules. Extensive inter-molecular O-H⋯O, N-H⋯O and C-H⋯O hydrogen bonds, π-π stacking inter-actions [centroid-centroid distances = 3.565 (14) and 3.425 (14) Å] and O⋯π inter-actions [O⋯centroid distance = 3.480 (2) Å] connect the various components in the crystal structure.
