Materials Data on Y2FeB by Materials Project

Abstract

Y2FeB crystallizes in the cubic F-43m space group. The structure is three-dimensional. there are two inequivalent Y sites. In the first Y site, Y is bonded to four equivalent Fe and six equivalent B atoms to form distorted YFe4B6 tetrahedra that share corners with eighteen YB4 tetrahedra and faces with sixteen YFe4B6 tetrahedra. All Y–Fe bond lengths are 2.79 Å. All Y–B bond lengths are 3.23 Å. In the second Y site, Y is bonded to four equivalent B atoms to form distorted YB4 tetrahedra that share corners with twenty-four YB4 tetrahedra and faces with four equivalent YFe4B6 tetrahedra. All Y–B bond lengths are 2.79 Å. Fe is bonded in a distorted body-centered cubic geometry to four equivalent Y and four equivalent B atoms. All Fe–B bond lengths are 2.79 Å. B is bonded in a 8-coordinate geometry to ten Y and four equivalent Fe atoms.
