The coordination polymer poly[bis[μ2-2-(2,2'-bi-1H-imidazol-1-yl)acetato]cadmium].

The title compound, [Cd(C(8)H(7)N(4)O(2))(2)](n), crystallizes in the centrosymmetric triclinic space group P1 with an asymmetric unit consisting of a bivalent Cd(II) atom and two 2-(2,2'-bi-1H-imidazol-1-yl)acetate (BDAC(-)) anions. Two inversion-related BDAC(-) ligands are oppositely arranged and bind two Cd(II) ions to form a [Cd(2)(BDAC)(2)] rhomboid subunit which is bridged by another BDAC(-) ligand to form an infinite ladder along the a direction containing parallelogram grids. The three-dimensional supramolecular architecture is formed by hydrogen bonds and C-H···π and π-π interactions.
