Abstract

Potassium peroxypentafluorotantalate monohydrate K2TaO2F5 · H2O was synthesized by the introduction of hydrogen peroxide and potassium chloride into highly pure tantalum-containing fluoride solutions at 70°C followed by cooling of the mixture to room temperature at a rate of 10–15 K/h. The X-ray diffraction analysis revealed that K2TaO2F5 · H2O crystallized in the monoclinic crystal system with the following unit cell parameters: a = 8.965(2) Å, b = 8.966(2) Å, c = 9.257(2) Å, β = 99.78(3) °, Z = 4, V unit cell = 733.3(5) Å3, ρcalcd = 3.681 g/cm3, FW = 404.13, space group C 32 = C2(5). The thermolysis of K2TaO2F5 · H2O was studied at 160–1000°C, and the phases formed under specified conditions were determined.
