The Ideal

The crystal structure of skutterudite-related phase IrGe1.5Se1.5 has been refined by the Rietveld method from laboratory X-ray powder diffraction data. Refined crystallographic data for IrGe1.5Se1.5 are a=12.0890(2) Å, c=14.8796(3) Å, V=1883.23(6) Å3, space group R3 (No. 148), Z=24, and Dc=8.87 g/cm3. Its crystal structure can be derived from the ideal skutterudite structure (CoAs3), where Se and Ge atoms are ordered in layers perpendicular to the [111] direction of the original skutterudite cell. Weak distortions of the anion and cation sublattices were also observed.

X-ray powder diffraction data for synthetic materials MgMnSiO4 and Mg0.6Mn1.4SiO4 are reported. Samples were prepared by firing mixtures of MgO, MnCO3, and SiO2 in prescribed molar ratios at 1523 K. Powder diffraction data were collected with a laboratory X-ray source (CuKα) for refinement of unit-cell parameters and synchrotron radiation (λ=1.1980 Å) for intensity measurement of individual reflections. Crystallographic data were MgMnSiO4, orthorhombic, Pnma (No. 62), a=10.4510(1), b=6.12446(5), c=4.80757(4) Å, V=307.717(4) Å3, Z=4, and Dx=3.697 g·cm−3, and Mg0.6Mn1.4SiO4, orthorhombic, Pnma (No. 62), a=10.5241(1), b=6.17903(6), c=4.83927(5) Å, V=314.692(5) Å3, Z=4, and Dx=3.873 g·cm−3.

The X-ray powder diffraction data of polycrystalline fibrillar zinc trimolybdates ZnMo3O10·3.75H2O, ZnMo3O10·5H2O, and ZnMo3O10·10H2O, are reported. An uncommon diffraction pattern was recorded in the case of the “wet fibers” of ZnMo3O10·10H2O, which could be indexed assuming a model of parallel fibers with translation disorder along the fiber axis. The powder diffraction patterns, lattice parameters, space groups, and other data describing these compounds are presented in this paper.© 1999 International Centre for Diffraction Data.
