Materials Data on Ho(CuGe)2 by Materials Project
HoCu2Ge2 crystallizes in the tetragonal I4/mmm space group. The structure is three-dimensional. Ho is bonded in a 8-coordinate geometry to eight equivalent Cu and eight equivalent Ge atoms. All Ho–Cu bond lengths are 3.28 Å. All Ho–Ge bond lengths are 3.11 Å. Cu is bonded to four equivalent Ho and four equivalent Ge atoms to form a mixture of distorted face, edge, and corner-sharing CuHo4Ge4 tetrahedra. All Cu–Ge bond lengths are 2.43 Å. Ge is bonded in a 9-coordinate geometry to four equivalent Ho, four equivalent Cu, and one Ge atom. The Ge–Ge bond length is 2.46 Å.
