摘　　要：Two new organic-inorganic hybrid mono-transition-metal-substituted polyoxometalates [Ni（2,2′-bipy）3]3[Ni（H2O）SiW11O39]·11H2O 1 and [Cu（dien）（H2O）][Cu（dien）（H2O）2]2- [CuSiW11O39]·5.5H2O 2 （2,2′-bipy = 2,2′-bipyridine, dien = diethylenetriamine） have been hydrothermally synthesized and characterized by single-crystal X-ray diffraction, elemental analysis, magnetic properties, and IR spectrum. Crystal data for 1： monoclinic, space group P21/n, a = 17.492（3）, b = 33.481（5）, c = 20.493（3）A^°, β = 101.894（3）°, Dc = 2.563 mg/A^°^3, F（000） = 8440, μ = 11.454 mm^-1 and Z = 4; and those for 2：monoclinic, space group P21/n, a = 11.114（3）, b = 22.803（7）, c = 22.468（7） A^°, β = 97.896（6）°, Dc = 4.036 mg/A^°^3, F（000） = 6140, μ = 23.942 mm^-1 and Z = 4. The study on the magnetic susceptibility of 2 demonstrates the presence of ferromagnetic interaction.Two new organic-inorganic hybrid mono-transition-metal-substituted polyoxometalates [Ni（2,2′-bipy）3]3[Ni（H2O）SiW11O39]·11H2O 1 and [Cu（dien）（H2O）][Cu（dien）（H2O）2]2- [CuSiW11O39]·5.5H2O 2 （2,2′-bipy = 2,2′-bipyridine, dien = diethylenetriamine） have been hydrothermally synthesized and characterized by single-crystal X-ray diffraction, elemental analysis, magnetic properties, and IR spectrum.
