Two new coordination polymers, namely, poly [[ 3 -3-(1H-benzimidazol-2-yl (2) have been synthesized from 3-(1H-benzoimidazol-2-yl)propanoic acid ligands through a mixedligand synthetic strategy under a solvothermal environment, and studied by single-crystal X-ray diffraction. Complex 1 crystallizes in the orthorhombic space group Pbca and features a two-dimensional structure formed by a binuclear Zn 2 O 4 core. Complex 2, however, crystallizes in the monoclinic space group P2 1 /c and forms a one-dimensional chain structure. The Zn II and Cd II ions have different coordination numbers and the 3-(1H-benzoimidazol-2-yl)-propanoate ligands display different coordination modes. The structures reported here show the importance of the selection of metal ions and suitable ligands.
