N2 - A novel polyoxovanadate (POV), [Zn(2,2′-bpy)3] 4[(ppz){{Zn(tepa)}2ZnAs8V13O 41(H2O)}2][As8V14O 42(0.5H2O)]2·4H2O (1, 2,2′-bpy = 2,2′-bipyridine, ppz = piperazine, tepa = tetraethylenepentamine), has been hydrothermally synthesized and structurally characterized by elemental analysis, IR spectra, thermogravimetric analysis, magnetic measurement, and single-crystal X-ray diffraction analysis. Crystal data for 1: orthorhombic, Aba2, a = 28.3414(14) Å, b = 27.9995(16) Å, c = 41.5819(16) Å, V = 32997(3) Å3, Z = 4, ρ = 2.264 mg·cm-3. X-ray structure analysis shows that the structure of 1 consists of one unique zinc-substituted POV dimer and two POV monomers. Interestingly, the formation of the zinc-substituted POV dimer involves two new in situ ligand reactions under hydrothermal conditions, the intermolecular and intramolecular deamination coupling reactions of dien. Magnetization measurement revealed the presence of antiferromagnetic interaction between VIV ions in 1.
