- Abstract
The new compound, KCr3(SO4)2(OH)6, was prepared by low-hydrothermal synthesis. The structure was refined by the Rietveld technique in space group R3m (Z = 3), a =7.2416(3) Å, c = 17.0788(9) Å, V = 775.63 Å3, Rp = 7.7, Rwp =10.1, RB = 6.8. The compound is isotypic with alunite, KAl3(SO4)2(OH)6. The temperature of decomposition under nitrogen atmosphere to a hitherto unknown form is about 550 K. The water content of alunite-type compounds is discussed.
