Each seven-coordinate CdII 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-BDOA2− 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-BDOA2− anions. Adjacent CdII atoms are bridged by two 1,3-BDOA2− ligands, forming a one-dimensional double-chain structure, with Cd…Cd separations of 4.014 (3) Å across the double chain and 13.105 (2) Å along the chain. A network of N—H…O interchain hydrogen bonds is also present.
