Materials Data on Tb2Fe17 by Materials Project
Tb2Fe17 crystallizes in the trigonal R-3m space group. The structure is three-dimensional. Tb is bonded in a 10-coordinate geometry to nineteen Fe atoms. There are a spread of Tb–Fe bond distances ranging from 3.01–3.27 Å. There are four inequivalent Fe sites. In the first Fe site, Fe is bonded to two equivalent Tb and ten Fe atoms to form FeTb2Fe10 cuboctahedra that share corners with fourteen FeTb2Fe10 cuboctahedra, edges with six equivalent FeTb3Fe9 cuboctahedra, and faces with ten FeTb2Fe10 cuboctahedra. There are a spread of Fe–Fe bond distances ranging from 2.43–2.60 Å. In the second Fe site, Fe is bonded in a 12-coordinate geometry to two equivalent Tb and ten Fe atoms. There are a spread of Fe–Fe bond distances ranging from 2.50–2.77 Å. In the third Fe site, Fe is bonded to three equivalent Tb and nine Fe atoms to form a mixture of corner, edge, and face-sharing FeTb3Fe9 cuboctahedra. There are two shorter (2.46 Å) and one longer (2.64 Å) Fe–Fe bond lengths. In the fourth Fe site, Fe is bonded in a 2-coordinate geometry to one Tb and thirteen Fe atoms. The Fe–Fe bond length is 2.40 Å.
