Self assembly of carboxylate/alcoholate functionalized ring-shape phosphomolybdates

Abstract

We report a simple and efficient approach to incorporate organic groups into polymolybdates by reaction of H₃PO₃ with Na₂MoO₄·2H₂O/(NH₄)₆Mo₇O₂₄·4H₂O and organic components in aqueous medium. Carboxylate and alcoholate ligands were covalently attached to the [HPMo₆O₂₁]²⁻ cluster to generate a series of inorganic–organic hybrid phosphomolybdates. Depending on the successful synthesis of these structures, it could be possible to obtain a variety of these hybrids through rational structural design using ligand control, which is rare in traditional “one-pot” polyoxometalate (POM) synthesis.
