Abstract: Each seven-coordinate Cd^II atom in the title coordination polymer, poly[[bis(1H-imidazole-N³)cadmium(II)]-₃-m-phenylenebis(oxyacetato)], [Cd(1,3-BDOA)(C₃H₄N₂)₂]_n (1,3-BDOA^2- is the benzene-1,3-dioxyacetate dianion, C₁₀H₈O₆), displays a distorted monocapped octahedral coordination geometry, defined by two N atoms from the imidazole ligands and five O atoms from three 1,3-BDOA^2- anions. Adjacent Cd^II atoms are bridged by two 1,3-BDOA^2- ligands, forming a one-dimensional double-chain structure, with CdCd separations of 4.014 (3) Å across the double chain and 13.105 (2) Å along the chain. A network of N-HO interchain hydrogen bonds is also present.
