Abstract: In the title one-dimensional coordination polymer, {[Co(4-CPOA)(3-PyOH)₂(H₂O)₂]·H₂O}_n [4-CPOA^2- is the 4-carboxyphenoxyacetate dianion (C₉H₆O₅^2-) and 3-PyOH is 3-hydroxypyridine (C₅H₅NO)], the Co^II atom has a distorted octahedral coordination geometry, defined by two carboxyl O-atom donors from two 4-CPOA^2- groups, two N-atom donors from two 3-PyOH co-ligands and two water molecules. The Co^II atoms are bridged by bis-monodentate carboxylate groups, forming a one-dimensional chain structure. The CoCo separation within the polymer is 10.862 (3) Å. The chains are linked into a three-dimensional supramolecular network via O-HO hydrogen bonds.
