Salts and double salts of rare earths, IV: Synthesis and crystal structure of caesium praseodymium sulfate


Crystals of the title compound were prepared by heating Cs[Pr(SO4)2(H2O)3]·H2O with H2SO4 at 300°C. CsPr(SO4)2 crystallizes in the orthorhombic space group Pnna witha=9.497(3),b=14.106(5),c=5.457(1) Å,p0=4.20,pc=4.236 gcm-3,Z=4. The structure, solved by the heavy-atom method from X-ray diffractometer data, was refined by least-squares techniques to R=0.023. The praseodymium atom is eight coordinated by eight oxygen atoms in the form of a distortedArchimedian antiprism. The antiprisms together with sulphur atoms form a layer-like structure parallel to thexz plane. The caesium atoms, which lie between the layers, have a coordination number of fourteen.
