摘要：

Peroxide ligation of aqueous metal-oxo clusters provides rich speciation and structural diversity. Here, three novel transition-metal derivatives of polyoxometalate anions, [Ni-2(H2O)(10){P4Ta6(O-2)(6)O-24}](6-) (1a), [Zn(H2O)(4){P4Ta6(O-2)(6)O-24}](8-) (2a) and [Cd(H2O)(4){P4Ta6(O-2)(6)O-24}](8-) (3a), have been successfully synthesized by adopting a one-pot reaction strategy. All of these hexatantalates are built from a new-type phosphorus-incorporated hexatantalates. We investigated the solution behaviors, and the peak assignments of the MS spectra indicated some degree of stability of them in water. Furthermore, the proton-conducting ability of compound la was also explored and it has shown well conductivity at high relative humidities, with conductivity achieved 1.22 x 10(-3) S/cm (85 degrees C, 90%RH).
