In the title compound, [Co(C10H12N2O)2(H2O)2](NO3)2·2H2O, the CoII 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 f1400ea-sb34 ligands and by two water molecules in a slightly distorted octahedral geometry.Intermolecular O—H.O hydrogen bonds link the cations, anions and water molecules into layers parallel to the ac plane.The crystal packing also exhibits weak intermolecular u11-200ps C—H.O hydrogen bonds.
