Through utilizing the flexible bis(triazole) ligand 1,3bis(1,2,4-triazol-1-y1)propane (btp), the new Keggin POM-templated compound, [Cd-2(H2O)(2)(btp)(4)(SiMo12O40)]center dot 2H(2)O (1), was synthesized under hydrothermal conditions. It was characterized by single-crystal X-ray diffraction, elemental analysis, IR spectroscopy, thermogravimetric analysis, photoluminescence spectroscopy, and cyclic voltammetry. In compound 1, the [SiMo12O40](4-) polyanions serving as template induce the Cd-bis(triazole) coordination polymer to construct a ladder-like chain. In the 1D chain, two btp ligands act as "middle rails". The template polyanions insert into the grids of the 1D chain. Furthermore, these chains can construct a 3D supramolecular structure through hydrogen bondings.
