Abstract

A rare-earth-containing polyoxometalate (RECP) hybrid, {(Yb (PDCH₂)₂(PDCH))·Na(H₂O)₂·(Na(PDCH)(H₂O)₂)}₂[P₂W₁₈O₆₂]·14H₂O (1), based on [P₂W₁₈O₆₂]⁶⁻ cluster anions and cationic Yb & Na complex units of pyridine-2,6-dicarboxylic acid (PDCH₂) has been synthesized under normal reaction conditions, which exhibited a supramolecular 3-D framework structure in the crystal lattice. Hybrid 1 acts as a green catalyst for the selective oxidation of sulfides in water with H₂O₂ as the reagent.
