Abstract: The title complex, [Co(2-OPA)₂(H₂O)₄] [2-OPA^- = (2-oxo-1,2-dihydropyridin-1-yl)acetate, C₇H₆NO], is a neutral mononuclear compound. The Co^II atom, located on an inversion center, has an octahedral coordination geometry involving two carbonyl O atoms of different 2-OPA^- ligands and four water molecules. A layer structure is formed via O-HO intermolecular hydrogen bonds.
