The first solid composed of [As4V16O42(H2O)] clusters.
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.
