A series of pH and time dependent POM-based compounds by using a double chelate ligand: Syntheses, structures and electrochemical properties

Three POM-based compounds were obtained by using a double chelate ligand. Compounds 1 and 2 were obtained under the same conditions except for different pH, while compounds 2 and 3 were also synthesized under the same conditions except for different reactive time. Compound 1 shows rare infinite Mo-O chains. Compound 2 is a discrete structure. In compound 3, a pair of [Ag(dpq)]+ subunits are connected by anions to form a 1D chain.
