Abstract: | Through utilizing the flexible bis(triazole) ligand 1,3‐bis(1,2,4‐triazol‐1‐y1)propane (btp), the new Keggin POM‐templated compound, [Cd2(H2O)2(btp)4(SiMo12O40)] · 2H2O ( 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. |
