Materials Data on Gd(Al3Ni)3 by Materials Project
GdNi3Al9 crystallizes in the trigonal R32 space group. The structure is three-dimensional. Gd is bonded in a 11-coordinate geometry to six equivalent Ni and eleven Al atoms. There are three shorter (3.29 Å) and three longer (3.30 Å) Gd–Ni bond lengths. There are a spread of Gd–Al bond distances ranging from 3.00–3.17 Å. Ni is bonded in a 8-coordinate geometry to two equivalent Gd and eight Al atoms. There are a spread of Ni–Al bond distances ranging from 2.33–2.63 Å. There are six inequivalent Al sites. In the first Al site, Al is bonded in a distorted trigonal non-coplanar geometry to one Gd, three equivalent Ni, and seven Al atoms. There are a spread of Al–Al bond distances ranging from 2.77–2.84 Å. In the second Al site, Al is bonded in a 2-coordinate geometry to two equivalent Gd, two equivalent Ni, and six Al atoms. There are two shorter (2.63 Å) and four longer (2.81 Å) Al–Al bond lengths. In the third Al site, Al is bonded in a linear geometry to two equivalent Ni and six Al atoms. There are two shorter (2.81 Å) and two longer (2.84 Å) Al–Al bond lengths. In the fourth Al site, Al is bonded in a 3-coordinate geometry to two equivalent Gd, three equivalent Ni, and five Al atoms. There are one shorter (2.71 Å) and one longer (2.78 Å) Al–Al bond lengths. In the fifth Al site, Al is bonded in a distorted trigonal non-coplanar geometry to three equivalent Ni and seven Al atoms. The Al–Al bond length is 2.87 Å. In the sixth Al site, Al is bonded in a distorted trigonal non-coplanar geometry to one Gd, three equivalent Ni, and seven Al atoms.
