Materials Data on Gd(Fe5Si)2 by Materials Project
Abstract
Gd(Fe5Si)2 crystallizes in the orthorhombic Immm space group. The structure is three-dimensional. Gd is bonded in a 12-coordinate geometry to sixteen Fe and four equivalent Si atoms. There are a spread of Gd–Fe bond distances ranging from 2.95–3.18 Å. All Gd–Si bond lengths are 3.09 Å. There are four inequivalent Fe sites. In the first Fe site, Fe is bonded in a 10-coordinate geometry to one Gd, eleven Fe, and two equivalent Si atoms. There are a spread of Fe–Fe bond distances ranging from 2.32–2.90 Å. Both Fe–Si bond lengths are 2.59 Å. In the second Fe site, Fe is bonded in a 10-coordinate geometry to one Gd, eleven Fe, and two equivalent Si atoms. There are a spread of Fe–Fe bond distances ranging from 2.41–2.65 Å. Both Fe–Si bond lengths are 2.51 Å. In the third Fe site, Fe is bonded in a 12-coordinate geometry to two equivalent Gd, eight Fe, and two equivalent Si atoms. All Fe–Fe bond lengths are 2.43 Å. Both Fe–Si bond lengths are 2.65 Å. In the fourth Fe site, Fe is bonded to two equivalent Gd, eight Fe, and two equivalent Si atoms to form distorted FeGd2Fe8Si2 cuboctahedra that share corners with fourmore »
