Abstract
Single crystals of Pr(ClO3)(3). 2H(2)O have been obtained from the reaction of Pr-2(CO3)(3). xH(2)O and HClO3. The crystal structure (orthorhombic, P2 (1)2(1)2(1), Z = 4, a = 576.03(7), b = 1236,7(2), c = 1314.0(2) pm) contain s Pr3+ ions coordinated by two H2O molecules and seven ClO3- groups. Accord ing to DTA/TG measurements, Pr(ClO3)(3). 2H(2)O decomposes in a two step me chanism with Pr(ClO3)(3) as an intermediate and PrOCl as the final product. The decomposition has also been investigated by means of temperature depen dent X-ray powder diffraction.
