In the title coordinaltion polymer, [Cd(C8H4O4)(C8H7N3)2]n, the CdII atom, lying on a twofold rotation axis, is six-coordinated by two carboxyl­ate O atoms from two benzene-1,3-dicarboxyl­ate (m-BDC) ligands and four N atoms from two chelating 2-(2-pyrid­yl)imidazole mol­ecules, forming a slightly distorted octa­hedral geometry. The m-BDC ligand is located over a twofold rotation axis. The CdII atoms are bridged by the m-BDC ligands, leading to a wave-shaped chain structure along [010]. N—H⋯O hydrogen bonds connect the chains.
