Materials Data on Fe3W by Materials Project

Abstract

WFe3 is Uranium Silicide structured and crystallizes in the cubic Pm-3m space group. The structure is three-dimensional. W is bonded to twelve equivalent Fe atoms to form WFe12 cuboctahedra that share corners with twelve equivalent WFe12 cuboctahedra, edges with twenty-four equivalent FeFe8W4 cuboctahedra, faces with six equivalent WFe12 cuboctahedra, and faces with twelve equivalent FeFe8W4 cuboctahedra. All W–Fe bond lengths are 2.56 Å. Fe is bonded to four equivalent W and eight equivalent Fe atoms to form distorted FeFe8W4 cuboctahedra that share corners with twelve equivalent FeFe8W4 cuboctahedra, edges with eight equivalent WFe12 cuboctahedra, edges with sixteen equivalent FeFe8W4 cuboctahedra, faces with four equivalent WFe12 cuboctahedra, and faces with fourteen equivalent FeFe8W4 cuboctahedra. All Fe–Fe bond lengths are 2.56 Å.
