Abstract: The asymmetric unit of the title one-dimensional coordination polymer, {[Co(C₁₀H₈N₂)(H₂O)₄](C₉H₆O₅)·H₂O}_n, comprises two half-cations, [Co(4,4'-bipy)(H₂O)₄]₂²⁺ (4,4'-bipy is 4,4'-bipyridine), one 3-carboxylatophenoxyacetate (3-CPOA^2-) dianion and one non-coordinated water molecule. The Co^II ions, both of which are located on inversion centres, have approximately octahedral geometries, involving two N atoms of the centrosymmetric 4,4'-bipy ligand and four water molecules. Adjacent Co^II atoms are linked by 4,4'-bipy ligands into a chain, the shortest CoCo separation within the polymeric chain being 11.456  (2)  Å. The chains are further linked by hydrogen-bonding and - stacking interactions, generating a three-dimensional network.
