Materials Data on Er3(Al2Fe)2 by Materials Project
Abstract
Er3(FeAl2)2 crystallizes in the triclinic P-1 space group. The structure is three-dimensional. there are three inequivalent Er sites. In the first Er site, Er is bonded in a 12-coordinate geometry to four Er, four Fe, and eight Al atoms. There are a spread of Er–Er bond distances ranging from 3.27–3.33 Å. There are a spread of Er–Fe bond distances ranging from 3.14–3.22 Å. There are a spread of Er–Al bond distances ranging from 3.11–3.22 Å. In the second Er site, Er is bonded in a 12-coordinate geometry to four Er, five Fe, and seven Al atoms. The Er–Er bond length is 3.21 Å. There are a spread of Er–Fe bond distances ranging from 3.06–3.21 Å. There are a spread of Er–Al bond distances ranging from 3.07–3.23 Å. In the third Er site, Er is bonded in a 12-coordinate geometry to four Er, three equivalent Fe, and nine Al atoms. There are a spread of Er–Er bond distances ranging from 3.29–3.31 Å. There are a spread of Er–Fe bond distances ranging from 3.15–3.19 Å. There are a spread of Er–Al bond distances ranging from 3.11–3.19 Å. There are three inequivalent Fe sites. In the first Fe site, Fe is bonded tomore »

In the first Fe site, Fe is bonded to six Er, two equivalent Fe, and four Al atoms to form FeEr6Al4Fe2 cuboctahedra that share corners with six FeEr6Al4Fe2 cuboctahedra, corners with twelve AlEr6Al4Fe2 cuboctahedra, edges with six FeEr6Al4Fe2 cuboctahedra, faces with four equivalent FeEr6Al4Fe2 cuboctahedra, and faces with fourteen AlEr6Al4Fe2 cuboctahedra.
