Synthesis and Characterization of Ligand-introduced [P2W12O44(C6H5PO3)2]10–

Lacunary polyoxometalates represent a distinctive category of inorganic multidentate ligands that serve as precursors for building organic–inorganic hybrid materials and multinuclear metal oxo clusters. In this study, we successfully synthesized and characterized the organic–inorganic hybrid, [P2W12O44(C6H5PO3)2]10−. Two phenylphosphonato ligands were introduced at both ends of the vacant site to form the unique organic–inorganic–organic structure.
