Materials Data on Cr3Fe by Materials Project

Abstract

Cr3Fe is Uranium Silicide structured and crystallizes in the cubic Pm-3m space group. The structure is three-dimensional. Cr is bonded to eight equivalent Cr and four equivalent Fe atoms to form CrCr8Fe4 cuboctahedra that share corners with twelve equivalent CrCr8Fe4 cuboctahedra, edges with eight equivalent FeCr12 cuboctahedra, edges with sixteen equivalent CrCr8Fe4 cuboctahedra, faces with four equivalent FeCr12 cuboctahedra, and faces with fourteen equivalent CrCr8Fe4 cuboctahedra. All Cr–Cr bond lengths are 2.53 Å. All Cr–Fe bond lengths are 2.53 Å. Fe is bonded to twelve equivalent Cr atoms to form FeCr12 cuboctahedra that share corners with twelve equivalent FeCr12 cuboctahedra, edges with twenty-four equivalent CrCr8Fe4 cuboctahedra, faces with six equivalent FeCr12 cuboctahedra, and faces with twelve equivalent CrCr8Fe4 cuboctahedra.
