Abstract The novel polyoxometalate,(H2NC4H8NH2)6［MoVI16VV12P2O84］·5H2O(1), was hydrothermally synthesized using NH4VO3, H3PMo12O40·xH2O, Cu(NO3)2 and piperazine as the starting materials. The structure and properties were characterized by UV-Vis， IR, XRD, XPS spectra and TG analysis. 1 belongs to monoclinic system, space group a=20.450(4) , b=24.989(5) , c=20.450(4) , β=93.89 °, V=10 427(4) 3, Fw=4 159.18, Dc=2.650 g·cm-3, μ=3.018 mm-1, F(000)=7 952, Gof=1.029.〖JP〗 The results showed that the polyanion ［P2Mol6V12O84］14- was a dipolymer formed by two ［PMo8V6O42］7- units. 1 exhibited a novel 3-D supramolecular arrays constructed from dipolymer anions and organic ligands via hydrogen bonds.
