The design and synthesis of high-nuclear polyoxometalates (POMs) constructed from pentagonal molecular building blocks (MBBs) are attractive and challenging. Herein, three new high-nuclear polyoxovanadates, including {V 20 W 2 P 20 } (1), {V 18 W 4 P 14 } (2), and {V 26 W 6 P 16 } (3), have been successfully synthesized under solvothermal conditions. All these structures are assembled from pentagonal MBB {WV 5 (PhPO 3 ) 5 } with different configurations. Compound 1 exhibits efficient, stable, and versatile catalytic activity for sulfide oxidation.
