A new polyoxovanadate [Zn2(dien)3][[Zn(dien)]2As4V16O42(H2O)] x 3H2O (1, dien = diethylenetriamine) has been hydrothermally synthesized and structurally characterized by EA, IR, TGA, magnetic measurement and single crystal X-ray diffraction. X-Ray diffraction analyses reveal that 1 exhibits the first [As4V16O42(H2O)]-containing polyoxometalate. In 1, the adjacent [As4V16O42(H2O)] clusters are linked to each other through dual mono-nuclear zinc complexes {Zn(dien)} to form one-dimensional anionic chains with isolated dinuclear zinc complexes [Zn2(dien)3] occupying the interchain regions as charge compensation. The study of the magnetic susceptibility demonstrates the presence of antiferromagnetic interaction between VIV cations in 1.
通过水热法合成了一种新型多金属氧酸盐[Zn2(dien)3][[Zn(dien)]2As4V16O42(H2O)]·3H2O（1，dien = 二乙烯三胺），并通过元素分析（EA）、红外光谱（IR）、热重分析（TGA）、磁性测量和单晶X射线衍射对其进行了结构表征。X射线衍射分析表明，1呈现出首例含[As4V16O42(H2O)]的多金属氧酸盐。在1中，相邻的[As4V16O42(H2O)]簇通过双单核锌配合物{Zn(dien)}相互连接，形成一维阴离子链，孤立的双核锌配合物[Zn2(dien)3]占据链间区域作为电荷补偿。磁化率研究表明1中VIV阳离子之间存在反铁磁相互作用。
