摘要

Single crystals of the hitherto unknown compound FeCe(WO4)(3) have been prepared by crystallization from melts of Fe2O3, CeO2 and WO3. It crystallizes with triclinic symmetry, space group P (1) over bar, a = 7,486(3); b = 7,528(1); c = 16,502(4) Angstrom, alpha = 101,00(2); beta = 96,62(3); gamma = 98,62 degrees; Z = 2. Tungsten shows octahedral and tetrahedral coordination by oxygen. The crystal structure is characterized by layers related to the Scheelite and Wolframite type. Thermogravimetric measurements led to a lost of oxygen during reaction. It results in a decrease of the oxidation states of Fe3+ and Ce4+ respectively, as will be discussed using magnetic measurements and calculations of the Coulomb terms of lattice energy. The structure contains a one-fold coordinated oxygen. References: 28
