摘要：

Indexed X-ray powder diffraction data are reported for the homologous compound (ZnO)(5)(In1-xYx)(2)O-3. The structures of (ZnO)(5)In2O3 and of (ZnO)(5)(In1-xYx)(2)O-3 were refined by the Rietveld technique on the basis of the space group R(3) over bar m. Refined unit cell dimensions are a 3.3285(1) A, c=58.127(2) A, V=557.71(3) Angstrom(3) D-x=6.11 g/cm(3), R-wp,, 10.52, R-B,= 8.56 for (ZnO)(5)In(2)o(3), and a=3.3505(1) Angstrom, c=57.863(1) Angstrom V=562.53(2) Angstrom(3), D-x=5.97 g/cm3, R-wp, = 9.05, R-B = 6.94 for (ZnO)(5)(In0.8Y0.2)(2)O-3. The structure of (ZnO)(5)In2O3 was shown to be isostructural with (ZnO)(5)LuFeO3. Y3+ ions were determined to be arranged at the 3a-metal sites substituting for In3+ ions.
