A new dimeric polyoxometalate derivate assembled by divacant Dawson {P2W16} units and isosceles triangle {Ce3} cluster

A rare [P2W16O59]12− ({P2W16})-based polyoxometalate derivative (TMA)10H5[Ce3(H2O)6(P2W16O59)2]⋅49H2O (1) was successfully synthesized, and polyanion of 1 consists of two divacant {P2W16} units connected by one standard isosceles triangle {Ce3} bridging cluster.205
