trans-Diaqua­bis[(E)-3-(dimethyl­amino)-1-(2-pyrid­yl)prop-2-en-1-one-κ2 N 1,O]cobalt(II) dinitrate dihydrate

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 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 C—H⋯O hydrogen bonds
