Title: Materials Data on SmErFe17 by Materials Project

Abstract

ErSmFe17 crystallizes in the trigonal R3m space group. The structure is three-dimensional. Er is bonded in a 10-coordinate geometry to nineteen Fe atoms. There are a spread of Er–Fe bond distances ranging from 3.02–3.27 Å. Sm is bonded in a 10-coordinate geometry to nineteen Fe atoms. There are a spread of Sm–Fe bond distances ranging from 3.03–3.28 Å. There are six inequivalent Fe sites. In the first Fe site, Fe is bonded to one Er, two equivalent Sm, and nine Fe atoms to form FeSm2ErFe9 cuboctahedra that share corners with fifteen FeSm2ErFe9 cuboctahedra, edges with eight FeSmEr2Fe9 cuboctahedra, and faces with ten FeSm2ErFe9 cuboctahedra. There are a spread of Fe–Fe bond distances ranging from 2.46–2.65 Å. In the second Fe site, Fe is bonded to two equivalent Er, one Sm, and nine Fe atoms to form FeSmEr2Fe9 cuboctahedra that share corners with fifteen FeSm2ErFe9 cuboctahedra, edges with eight FeSmEr2Fe9 cuboctahedra, and faces with ten FeSm2ErFe9 cuboctahedra. There are a spread of Fe–Fe bond distances ranging from 2.45–2.64 Å. In the third Fe site, Fe is bonded to one Er, one Sm, and ten Fe atoms to form FeSmErFe10 cuboctahedra that share corners with fourteen FeSmEr2Fe9 cuboctahedra, edges with six FeSmEr2Fe9more » cuboctahedra, and faces with ten FeSm2ErFe9 cuboctahedra. There are a spread of Fe–Fe bond distances ranging from 2.43–2.61 Å. In the fourth Fe site, Fe is bonded in a 12-coordinate geometry to one Er, one Sm, and ten Fe atoms. There are a spread of Fe–Fe bond distances ranging from 2.48–2.77 Å. In the fifth Fe site, Fe is bonded in a 2-coordinate geometry to one Er and thirteen Fe atoms. The Fe–Fe bond length is 2.40 Å. In the sixth Fe site, Fe is bonded in a 2-coordinate geometry to one Sm and thirteen Fe atoms.« less
