Ni3Fe is Uranium Silicide structured and crystallizes in the cubic Pm-3m space group. Fe(1) is bonded to twelve equivalent Ni(1) atoms to form FeNi12 cuboctahedra that share corners with twelve equivalent Fe(1)Ni12 cuboctahedra, edges with twenty-four equivalent Ni(1)Fe4Ni8 cuboctahedra, faces with six equivalent Fe(1)Ni12 cuboctahedra, and faces with twelve equivalent Ni(1)Fe4Ni8 cuboctahedra. Ni(1) is bonded to four equivalent Fe(1) and eight equivalent Ni(1) atoms to form NiFe4Ni8 cuboctahedra that share corners with twelve equivalent Ni(1)Fe4Ni8 cuboctahedra, edges with eight equivalent Fe(1)Ni12 cuboctahedra, edges with sixteen equivalent Ni(1)Fe4Ni8 cuboctahedra, faces with four equivalent Fe(1)Ni12 cuboctahedra, and faces with fourteen equivalent Ni(1)Fe4Ni8 cuboctahedra.
