Abstract

K3Nb3WO9(AsO4)2 has been investigated by means of X-ray powder diffraction. Powder diffraction data were obtained by conventional diffractometer with Kα radiation. Unit-cell dimensions were determined by an indexing program based on variation of parameters by successive dichotomies. An orthorhombic cell (space group Pnma) was found with a=15.001 (1) Å, b=14.814(1) Å, c=7.2374 (8) Å, and V=1608.4 (4) A3. The figures of merit were calculated to be M(20)=35.9 and F(20)=70.8 (0.0055,51).
