Abstract: In the title coordination polymer, [Cu(1,4-BDOA)(2,2'-bipy)(H₂O)]_n (where 1,4-BDOA^2- is benzene-1,4-dioxyacetate, C₁₀H₈O₆, and 2,2'-bipy is 2,2'-bipyridine, C₁₀H₈N₂), each Cu^II atom is six-coordinate and displays a distorted square-pyramidal geometry, with the basal plane capped by one very long semicoordinate Cu-O bond of 2.920 (3) Å. Adjacent Cu^II ions are bridged by carboxylate groups, resulting in a one-dimensional chain structure with a shortest CuCu distance of 13.484 (3) Å. Furthermore, these chains are linked through hydrogen bonds and - stacking interactions to form a supramolecular network.
