Materials Data on TmAlFe by Materials Project
Abstract
TmFeAl crystallizes in the orthorhombic Amm2 space group. The structure is three-dimensional. there are two inequivalent Tm sites. In the first Tm site, Tm is bonded in a 12-coordinate geometry to three equivalent Tm, five Fe, and seven Al atoms. There are one shorter (3.24 Å) and two longer (3.25 Å) Tm–Tm bond lengths. There are a spread of Tm–Fe bond distances ranging from 2.98–3.16 Å. There are a spread of Tm–Al bond distances ranging from 3.10–3.15 Å. In the second Tm site, Tm is bonded in a 12-coordinate geometry to four Tm, seven Fe, and five Al atoms. The Tm–Tm bond length is 3.03 Å. There are a spread of Tm–Fe bond distances ranging from 3.04–3.16 Å. There are a spread of Tm–Al bond distances ranging from 3.00–3.17 Å. There are three inequivalent Fe sites. In the first Fe site, Fe is bonded to six Tm and six Al atoms to form FeTm6Al6 cuboctahedra that share corners with four equivalent AlTm6Al2Fe4 cuboctahedra, corners with six FeTm6Al6 cuboctahedra, edges with six FeTm6Al6 cuboctahedra, and faces with fourteen AlTm6Al2Fe4 cuboctahedra. There are a spread of Fe–Al bond distances ranging from 2.59–2.71 Å. In the second Fe site, Fe is bonded inmore »
