Structure of Dy13Zn57 a binary quasicrystal approximant

Pay Gómez, Cesar and Lidin, Sven LU (2002) In Solid State Sciences 4(7). p.901-906
Abstract

The title compound Dy13Zn57, crystallizes in the orthorhombic space group Pnma (No. 62) with the cell parameters a = 14.060(5), b = 14.260(5) and c = 24.700(3) Å. The structure has formerly been described as Dy13Zn58 with the hexagonal type structure of Gd13Zn58. Single-crystal X-ray diffraction measurements however, show extra reflections breaking the C-centering of the corresponding orthorhombic cell with the parameters ao ≈ ch, bo ≈ ah and co ≈ √3 × ah and thereby making it primitive. The title compound is comprised of structural building units that also are encountered in the other... (More)

The title compound Dy13Zn57, crystallizes in the orthorhombic space group Pnma (No. 62) with the cell parameters a = 14.060(5), b = 14.260(5) and c = 24.700(3) Å. The structure has formerly been described as Dy13Zn58 with the hexagonal type structure of Gd13Zn58. Single-crystal X-ray diffraction measurements however, show extra reflections breaking the C-centering of the corresponding orthorhombic cell with the parameters ao ≈ ch, bo ≈ ah and co ≈ √3 × ah and thereby making it primitive. The title compound is comprised of structural building units that also are encountered in the other RE13Zn58 (RE = rare earth) compounds, the related RE13Cd58, the RECd6 phases and the newly found binary quasicrystal YbCd5.7.
