catena-Poly[[bis[2-(2-pyridyl)-1-H-imidazole-κ2N2,N3]cadmium]-μ-benzene-1,3-dicarboxylato-κ2O1:O3]

Abstract

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.
