Abstract

The crystal structure of Bi0.7Yb1.3WO6 (a representative of the isomorphous series Bi(2-x)Ln(x)WO(6); 0.3 < x < 1.3, for most lanthanides) has been determined. Contrary to previous suggestions, this structure type (space group A2, a = 8.1070(3) Angstrom, b = 3.7048(2) Angstrom, c = 15.8379(8) Angstrom, beta = 103.548(4)degrees) contains layers of stoichiometry WO4, containing WO6 octahedra sharing both edges and corners. These layers alternate with fluorite-like (Bi/Yb)(2)O-2 sheets; this is a novel and unexpected arrangement and contrasts dramatically with the purely corner-sharing octahedral WO4-layer in the parent Aurivillius phase Bi2WO6.
