Abstract: In the title Co^II polymeric complex bridged by tartrate dianions, {[Co(C₄H₄O₆)(H₂O)₂]·H₂O}_n, the Co^II atom is coordinated by two tartrate dianions and two water molecules to give a distorted octahedral geometry. The hydroxyl O atom and one O atom of each carboxyl group chelate to the Co^II atom, but the other O atom of this carboxyl group is uncoordinated. The polymeric chains are linked to each other via hydrogen bonds to form cavities which are filled with solvent water molecules.
