Materials Data on DyAlSi by Materials Project

Abstract

DyAlSi crystallizes in the tetragonal I4_1md space group. The structure is three-dimensional. Dy is bonded to six equivalent Al and six equivalent Si atoms to form a mixture of edge and face-sharing DyAl6Si6 cuboctahedra. There are four shorter (3.14 Å) and two longer (3.16 Å) Dy–Al bond lengths. There are four shorter (3.12 Å) and two longer (3.19 Å) Dy–Si bond lengths. Al is bonded in a distorted trigonal planar geometry to six equivalent Dy and three equivalent Si atoms. All Al–Si bond lengths are 2.39 Å. Si is bonded in a distorted trigonal planar geometry to six equivalent Dy and three equivalent Al atoms.
