Materials Data on AlFe2Si by Materials Project
Fe2AlSi is Heusler structured and crystallizes in the cubic Fm-3m space group. The structure is three-dimensional. Fe is bonded in a body-centered cubic geometry to four equivalent Al and four equivalent Si atoms. All Fe–Al bond lengths are 2.42 Å. All Fe–Si bond lengths are 2.42 Å. Al is bonded in a distorted body-centered cubic geometry to eight equivalent Fe and six equivalent Si atoms. All Al–Si bond lengths are 2.80 Å. Si is bonded in a distorted body-centered cubic geometry to eight equivalent Fe and six equivalent Al atoms.
