Abstract: In the title compound, [Co(C₁₀H₁₂N₂O)₂(H₂O)₂](NO₃)₂·2H₂O, the Co^II ion, located on an inversion center, is trans-coordinated by two N,O-bidentate chelating (E)-3-(dimethylamino)-1-(2-pyridyl)prop-2-en-1-one ligands and by two water molecules in a slightly distorted octahedral geometry. Intermolecular O-HO hydrogen bonds link the cations, anions and water molecules into layers parallel to the ac plane. The crystal packing also exhibits weak intermolecular C-HO hydrogen bonds.
