摘　　要：One new arsenic-vanadium cluster, [Zn（dien）（Hdien）]2[As6V15O42（H2O）]·4H2O （1, dien = diethylenetriamine）, has been hydrothermally synthesized and characterized by IR, elemental analysis, TGA, magnetic property and single-crystal X-ray diffraction analysis. Crystal data for 1： monoclinic, space group P21/n, a = 13.959（3）, b = 22.428（5）, c = 22.831（5） A^°, β = 90.733（4）°, Z = 4. X-ray crystallographic study showed that compound 1 is constructed from [As6V15O42（H2O）]^6- polyoxoanions linked together by novel [Zn（dien）（Hdien）]^3＋ complex fragments via hydrogen bonds into a three-dimensional network. Variable temperature susceptibility measurement demonstrates the presence of antiferromagnetic interaction between V^IV cations in 1.One new arsenic-vanadium cluster, [Zn（dien）（Hdien）]2[As6V15O42（H2O）]·4H2O （1, dien = diethylenetriamine）, has been hydrothermally synthesized and characterized by IR, elemental analysis, TGA, magnetic property and single-crystal X-ray diffraction analysis.
