Materials Data on FeCo3 by Materials Project

Abstract

FeCo3 is Uranium Silicide structured and crystallizes in the cubic Pm-3m space group. The structure is three-dimensional. Fe is bonded to twelve equivalent Co atoms to form FeCo12 cuboctahedra that share corners with twelve equivalent FeCo12 cuboctahedra, edges with twenty-four equivalent CoFe4Co8 cuboctahedra, faces with six equivalent FeCo12 cuboctahedra, and faces with twelve equivalent CoFe4Co8 cuboctahedra. All Fe–Co bond lengths are 2.50 Å. Co is bonded to four equivalent Fe and eight equivalent Co atoms to form CoFe4Co8 cuboctahedra that share corners with twelve equivalent CoFe4Co8 cuboctahedra, edges with eight equivalent FeCo12 cuboctahedra, edges with sixteen equivalent CoFe4Co8 cuboctahedra, faces with four equivalent FeCo12 cuboctahedra, and faces with fourteen equivalent CoFe4Co8 cuboctahedra. All Co–Co bond lengths are 2.50 Å.
