Abstract: The Co^II atom in the title coordination polymer, [Co(1,4-BDOA)(H₂O)₄]_n (where 1,4-BDOA^2- is benzene-1,4-dioxyacetate, C₁₀H₈O₆), lies on an inversion center. The Co^II atom has an octahedral coordination configuration, involving two carboxyl O atoms of different benzene-1,4-dioxyacetate ligands and four water molecules. Adjacent Co^II atoms are bridged by anions with two monodentate carboxylate groups, forming a one-dimensional chain along the c axis; the CoCo separation within the polymer is 14.699 (2) Å. A supramolecular network structure is formed by O-HO hydrogen bonds.
