 Title    Zur Kristallstruktur von Ce2(W 0 4)3 On the Crystal Structure of Ce2(W 0 4)3  
 Abstract    Single crystals of Ce2(W 0 4)3 have been prepared by crystallisation from molten mixtures of W 0 3 and C e 0 2. The compound shows m onoclinic symmetry, a = 7.813(4), b = 11.720(2), c = 11.586(3), ß = 109.36(3)°, Z = 4, and is isotypic to Eu2(W 0 4)3, but shows large differences of the atomic coordinates especially of oxygen. The crystal structure of Ce2(W 0 4)3 is charac­ terized by W (1)0 4 tetrahedra, square W (2)0 5 pyramids and a distorted capped trigonal prism of oxygen around cerium. The decrease o f the oxidation states of C e4+ or W6+ was proved by thermogravimetric and magnetic measurements as well as by calculations of the Coulomb terms of lattice energy.
