Materials Data on GaFe4Co8Si3 by Materials Project

Abstract

Fe4Co8GaSi3 is Tungsten-derived structured and crystallizes in the trigonal R-3m space group. The structure is three-dimensional. there are two inequivalent Fe sites. In the first Fe site, Fe is bonded in a distorted body-centered cubic geometry to eight Co atoms. There are a spread of Fe–Co bond distances ranging from 2.40–2.45 Å. In the second Fe site, Fe is bonded in a distorted body-centered cubic geometry to eight Co atoms. There are a spread of Fe–Co bond distances ranging from 2.43–2.51 Å. There are eight inequivalent Co sites. In the first Co site, Co is bonded in a body-centered cubic geometry to four equivalent Fe, three equivalent Ga, and one Si atom. There are three shorter (2.43 Å) and one longer (2.51 Å) Co–Fe bond lengths. All Co–Ga bond lengths are 2.47 Å. The Co–Si bond length is 2.39 Å. In the second Co site, Co is bonded in a body-centered cubic geometry to four equivalent Fe and four Si atoms. There are one shorter (2.44 Å) and three longer (2.45 Å) Co–Si bond lengths. In the third Co site, Co is bonded in a body-centered cubic geometry to four Fe and four Si atoms. There are one shorter (2.44 Å) and three longer (2.45 Å) Co–Si bond lengths. In the fourth Co site, Co is bonded in a body-centered cubic geometry to four equivalent Fe, three equivalent Ga, and one Si atom. All Co–Ga bond lengths are 2.47 Å. The Co–Si bond length is 2.39 Å. In the fifth Co site, Co is bonded in a body-centered cubic geometry to four Fe, one Ga, and three equivalent Si atoms. The Co–Ga bond length is 2.51 Å. All Co–Si bond lengths are 2.43 Å. In the sixth Co site, Co is bonded in a body-centered cubic geometry to four equivalent Fe, three equivalent Ga, and one Si atom. All Co–Ga bond lengths are 2.47 Å. The Co–Si bond length is 2.39 Å. In the seventh Co site, Co is bonded in a body-centered cubic geometry to four equivalent Fe and four Si atoms. There are one shorter (2.43 Å) and three longer (2.44 Å) Co–Fe bond lengths. There are one shorter (2.44 Å) and three longer (2.45 Å) Co–Si bond lengths. In the eighth Co site, Co is bonded in a body-centered cubic geometry to four equivalent Fe and four Si atoms. There are one shorter (2.43 Å) and three longer (2.44 Å) Co–Fe bond lengths. There are one shorter (2.44 Å) and three longer (2.45 Å) Co–Si bond lengths. Ga is bonded in a distorted body-centered cubic geometry to eight Co atoms. There are two inequivalent Si sites. In the first Si site, Si is bonded in a distorted body-centered cubic geometry to eight Co atoms. In the second Si site, Si is bonded in a distorted body-centered cubic geometry to eight Co atoms.
