Abstract: In the title coordination polymer, also called catena-poly[[aquabis(1H-imidazole-N³)copper(II)]--phenylenedioxydiacetato-²O:O'], [Cu(1,4-BDOA)(C₃H₄N₂)₂(H₂O)]_n (where 1,4-BDOA^2- is benzene-1,4-dioxyacetate, C₁₀H₈O₆), the Cu^II atom is five-coordinate involving two O atoms of the 1,4-BDOA ligand, two N atoms of imidazole ligands and one water molecule, displaying a distorted square-pyramidal coordination geometry. The Cu^II atoms are bridged by carboxylate groups, forming a one-dimensional zigzag chain. The adjacent CuCu distance is 12.656 (5) Å. Furthermore, such chains are linked by hydrogen-bond interactions, resulting in a three-dimensional network.
