Title: Materials Data on Tb3(Al2Fe)2 by Materials Project

Abstract

Tb3(FeAl2)2 crystallizes in the triclinic P-1 space group. The structure is three-dimensional. there are three inequivalent Tb sites. In the first Tb site, Tb is bonded in a 12-coordinate geometry to four Fe and eight Al atoms. There are a spread of Tb–Fe bond distances ranging from 3.18–3.26 Å. There are a spread of Tb–Al bond distances ranging from 3.14–3.27 Å. In the second Tb site, Tb is bonded in a 12-coordinate geometry to five Fe and seven Al atoms. There are a spread of Tb–Fe bond distances ranging from 3.09–3.24 Å. There are a spread of Tb–Al bond distances ranging from 3.11–3.25 Å. In the third Tb site, Tb is bonded in a 12-coordinate geometry to three equivalent Fe and nine Al atoms. There are a spread of Tb–Fe bond distances ranging from 3.21–3.23 Å. There are a spread of Tb–Al bond distances ranging from 3.15–3.24 Å. There are three inequivalent Fe sites. In the first Fe site, Fe is bonded to six Tb, two equivalent Fe, and four Al atoms to form FeTb6Al4Fe2 cuboctahedra that share corners with six FeTb6Al4Fe2 cuboctahedra, corners with twelve AlTb6Al4Fe2 cuboctahedra, edges with six FeTb6Al4Fe2 cuboctahedra, faces with four equivalent FeTb6Al4Fe2 cuboctahedra, andmore » faces with fourteen AlTb6Al4Fe2 cuboctahedra. Both Fe–Fe bond lengths are 2.71 Å. There are two shorter (2.66 Å) and two longer (2.71 Å) Fe–Al bond lengths.

There are two shorter (2.64 Å) and two longer (2.74 Å) Fe–Al bond lengths. There are five inequivalent Al sites.

In the second Al site, Al is bonded to six Tb, three Fe, and three Al atoms to form distorted AlTb6Al3Fe3 cuboctahedra that share corners with six FeTb6Al4Fe2 cuboctahedra, corners with twelve AlTb6Al4Fe2 cuboctahedra, edges with six equivalent AlTb6Al3Fe3 cuboctahedra, faces with nine FeTb6Al4Fe2 cuboctahedra, and faces with nine AlTb6Al4Fe2 cuboctahedra. There are one shorter (2.72 Å) and one longer (2.77 Å) Al–Al bond lengths. In the third Al site, Al is bonded to six equivalent Tb, two equivalent Fe, and four Al atoms to form AlTb6Al4Fe2 cuboctahedra that share corners with four equivalent FeTb6Al6 cuboctahedra, corners with fourteen AlTb6Al3Fe3 cuboctahedra, edges with six equivalent AlTb6Al4Fe2 cuboctahedra, faces with six equivalent FeTb6Al6 cuboctahedra, and faces with twelve AlTb6Al4Fe2 cuboctahedra. Both Al–Al bond lengths are 2.77 Å.
