Materials Data on HoGeAu by Materials Project

HoAuGe is half-Heusler structured and crystallizes in the cubic F-43m space group. The structure is three-dimensional. Ho is bonded to four equivalent Au and six equivalent Ge atoms to form a mixture of distorted corner and face-sharing HoGe6Au4 tetrahedra. All Ho–Au bond lengths are 2.82 Å. All Ho–Ge bond lengths are 3.26 Å. Au is bonded in a body-centered cubic geometry to four equivalent Ho and four equivalent Ge atoms. All Au–Ge bond lengths are 2.82 Å. Ge is bonded in a 4-coordinate geometry to six equivalent Ho and four equivalent Au atoms.

Materials Data on HoGeAu by Materials Project

HoAuGe crystallizes in the hexagonal P6_3mc space group. The structure is three-dimensional. Ho is bonded in a 12-coordinate geometry to six equivalent Au and six equivalent Ge atoms. There are three shorter (2.99 Å) and three longer (3.35 Å) Ho–Au bond lengths. There are three shorter (2.99 Å) and three longer (3.35 Å) Ho–Ge bond lengths. Au is bonded in a 10-coordinate geometry to six equivalent Ho and four equivalent Ge atoms. There are three shorter (2.66 Å) and one longer (3.03 Å) Au–Ge bond lengths. Ge is bonded in a 10-coordinate geometry to six equivalent Ho and four equivalent Au atoms.
