Assembly of Zn and Cd coordination polymers with different dimensionalities based on the semi-flexible 3-(1-benzimidazol-2-yl)propanoic acid ligand.

Two new coordination polymers, namely, poly[[μ-3-(1-benzimidazol-2-yl)propionato]zinc(II)], [Zn(CHNO)] , (), and poly[bis-[μ-3-(1-benzimid-azol-2-yl)propionato]cadmium(II)], [Cd(CHNO)] , () have been synthesized from 3-(1-benzoimidazol-2-yl)propanoic acid ligands through a mixed-ligand synthetic strategy under a solvothermal environment, and studied by single-crystal X-ray diffraction. Complex crystallizes in the ortho-rhom-bic space group and features a two-dimensional structure formed by a binuclear ZnO core. Complex , however, crystallizes in the monoclinic space group 2/ and forms a one-dimensional chain structure.
