Materials Data on GdAlSi by Materials Project

Abstract

GdAlSi crystallizes in the tetragonal I4_1md space group. The structure is three-dimensional. Gd is bonded to six equivalent Al and six equivalent Si atoms to form a mixture of edge and face-sharing GdAl6Si6 cuboctahedra. There are four shorter (3.17 Å) and two longer (3.19 Å) Gd–Al bond lengths. There are four shorter (3.17 Å) and two longer (3.20 Å) Gd–Si bond lengths. Al is bonded in a distorted trigonal planar geometry to six equivalent Gd and three equivalent Si atoms. There are one shorter (2.40 Å) and two longer (2.41 Å) Al–Si bond lengths. Si is bonded in a distorted trigonal planar geometry to six equivalent Gd and three equivalent Al atoms.
