Materials Data on FeCuNi by Materials Project

Abstract

FeNiCu is alpha La-derived structured and crystallizes in the trigonal P3m1 space group. The structure is three-dimensional. Fe is bonded to six equivalent Fe, three equivalent Ni, and three equivalent Cu atoms to form FeFe6Cu3Ni3 cuboctahedra that share corners with three equivalent NiFe3Cu3Ni6 cuboctahedra, corners with three equivalent CuFe3Cu6Ni3 cuboctahedra, corners with six equivalent FeFe6Cu3Ni3 cuboctahedra, edges with six equivalent FeFe6Cu3Ni3 cuboctahedra, edges with nine equivalent NiFe3Cu3Ni6 cuboctahedra, edges with nine equivalent CuFe3Cu6Ni3 cuboctahedra, faces with six equivalent FeFe6Cu3Ni3 cuboctahedra, faces with six equivalent NiFe3Cu3Ni6 cuboctahedra, and faces with six equivalent CuFe3Cu6Ni3 cuboctahedra. All Fe–Fe bond lengths are 2.47 Å. All Fe–Ni bond lengths are 2.41 Å. All Fe–Cu bond lengths are 2.55 Å. Ni is bonded to three equivalent Fe, six equivalent Ni, and three equivalent Cu atoms to form NiFe3Cu3Ni6 cuboctahedra that share corners with three equivalent FeFe6Cu3Ni3 cuboctahedra, corners with three equivalent CuFe3Cu6Ni3 cuboctahedra, corners with six equivalent NiFe3Cu3Ni6 cuboctahedra, edges with six equivalent NiFe3Cu3Ni6 cuboctahedra, edges with nine equivalent FeFe6Cu3Ni3 cuboctahedra, edges with nine equivalent CuFe3Cu6Ni3 cuboctahedra, faces with six equivalent FeFe6Cu3Ni3 cuboctahedra, faces with six equivalent NiFe3Cu3Ni6 cuboctahedra, and faces with six equivalent CuFe3Cu6Ni3 cuboctahedra. All Ni–Ni bond lengths are 2.47 Å. All Ni–Cu bond lengths are 2.55 Å. Cu is bonded to three equivalent Fe, three equivalent Ni, and six equivalent Cu atoms to form CuFe3Cu6Ni3 cuboctahedra that share corners with three equivalent FeFe6Cu3Ni3 cuboctahedra, corners with three equivalent NiFe3Cu3Ni6 cuboctahedra, corners with six equivalent CuFe3Cu6Ni3 cuboctahedra, edges with six equivalent CuFe3Cu6Ni3 cuboctahedra, edges with nine equivalent FeFe6Cu3Ni3 cuboctahedra, edges with nine equivalent NiFe3Cu3Ni6 cuboctahedra, faces with six equivalent FeFe6Cu3Ni3 cuboctahedra, faces with six equivalent NiFe3Cu3Ni6 cuboctahedra, and faces with six equivalent CuFe3Cu6Ni3 cuboctahedra. All Cu–Cu bond lengths are 2.47 Å.
