| Abstract: The new potassium peroxyniobatungstate ［K8H4Nb4W8O36(O2)4·18H2O］ was prepared by white powdery tungstic acid, potassium niobate and hydrogen peroxide. The crystal structure was determined by X-ray single crystal diffraction techniques. The crystal belongs to cubic system with space group Pm3-m. The unit cell parameters are a=1.064(1) nm, V=1.205(5) nm3, Z=1 D=4.388 g/cm3. |
