12Molybdophosphoric

12Molybdophosphoric acid is a chemical compound with the formula H3PMo12O40. It is a member of the polyoxometalate family, which are discrete, molecular metal-oxygen clusters. 12Molybdophosphoric acid is characterized by its high acidity and its ability to form stable complexes with various metal ions.

The compound is typically prepared by the reaction of phosphoric acid with molybdenum trioxide in the presence of a strong acid, such as sulfuric acid. The resulting solution is then concentrated and cooled to obtain the crystalline product. The structure of 12Molybdophosphoric acid consists of a central phosphorus atom surrounded by 12 molybdenum atoms, which are further coordinated by oxygen atoms.

The acidity of 12Molybdophosphoric acid is due to the presence of the phosphorus atom, which can donate protons to form the conjugate base, H2PMo12O40. This base is known to form stable complexes with a wide range of metal ions, including transition metals, lanthanides, and actinides. These complexes are often used in catalysis, materials science, and analytical chemistry.

12Molybdophosphoric acid is also of interest in the field of supramolecular chemistry, where it can act as a building block for the construction of more complex polyoxometalate-based materials. Its high acidity and ability to form stable complexes make it a versatile compound for various applications in chemistry and materials science.
