Materials Data on HoCuGe by Materials Project

HoCuGe is hexagonal omega structure-derived structured and crystallizes in the hexagonal P6_3/mmc space group. The structure is three-dimensional. Ho is bonded to six equivalent Cu and six equivalent Ge atoms to form a mixture of face and edge-sharing HoCu6Ge6 cuboctahedra. All Ho–Cu bond lengths are 3.05 Å. All Ho–Ge bond lengths are 3.05 Å. Cu is bonded in a 9-coordinate geometry to six equivalent Ho and three equivalent Ge atoms. All Cu–Ge bond lengths are 2.44 Å. Ge is bonded in a 9-coordinate geometry to six equivalent Ho and three equivalent Cu atoms.
