Materials Data on FeNi2Ge by Materials Project

Abstract

Ni2FeGe is alpha La-derived structured and crystallizes in the tetragonal P4/mmm space group. The structure is three-dimensional. Fe is bonded to eight equivalent Ni and four equivalent Ge atoms to form FeNi8Ge4 cuboctahedra that share corners with twelve equivalent FeNi8Ge4 cuboctahedra, edges with eight equivalent GeFe4Ni8 cuboctahedra, edges with sixteen equivalent NiFe4Ni4Ge4 cuboctahedra, faces with four equivalent GeFe4Ni8 cuboctahedra, faces with six equivalent FeNi8Ge4 cuboctahedra, and faces with eight equivalent NiFe4Ni4Ge4 cuboctahedra. All Fe–Ni bond lengths are 2.54 Å. All Fe–Ge bond lengths are 2.49 Å. Ni is bonded to four equivalent Fe, four equivalent Ni, and four equivalent Ge atoms to form NiFe4Ni4Ge4 cuboctahedra that share corners with twelve equivalent NiFe4Ni4Ge4 cuboctahedra, edges with eight equivalent FeNi8Ge4 cuboctahedra, edges with eight equivalent NiFe4Ni4Ge4 cuboctahedra, edges with eight equivalent GeFe4Ni8 cuboctahedra, faces with four equivalent FeNi8Ge4 cuboctahedra, faces with four equivalent GeFe4Ni8 cuboctahedra, and faces with ten equivalent NiFe4Ni4Ge4 cuboctahedra. All Ni–Ni bond lengths are 2.49 Å. All Ni–Ge bond lengths are 2.54 Å. Ge is bonded to four equivalent Fe and eight equivalent Ni atoms to form GeFe4Ni8 cuboctahedra that share corners with twelve equivalent GeFe4Ni8 cuboctahedra, edges with eight equivalent FeNi8Ge4 cuboctahedra, edges with sixteen equivalent NiFe4Ni4Ge4 cuboctahedra, faces with four equivalent FeNi8Ge4 cuboctahedra, faces with six equivalent GeFe4Ni8 cuboctahedra, and faces with eight equivalent NiFe4Ni4Ge4 cuboctahedra.
