catena-Poly[[aquabis(1H-imidazole-κN3)copper(II)]-μ-benzene-1,4-dioxyacetato-κ2O:O′]

In the title coordination polymer, also called catena-poly[[aquabis(1H-imidazole-kappaN(3)) copper(II)]-mu-phenylenedioxydiacetato-kappa(2) O: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 Cu...Cu distance is 12.656 (5) Angstrom. Furthermore, such chains are linked by hydrogen-bond interactions, resulting in a three-dimensional network.
