Materials Data on Ho(MnGe)2 by Materials Project
HoMn2Ge2 crystallizes in the tetragonal I4/mmm space group. The structure is three-dimensional. Ho is bonded in a 8-coordinate geometry to eight equivalent Ge atoms. All Ho–Ge bond lengths are 3.06 Å. Mn is bonded to four equivalent Ge atoms to form a mixture of corner and edge-sharing MnGe4 tetrahedra. All Mn–Ge bond lengths are 2.43 Å. Ge is bonded in a 9-coordinate geometry to four equivalent Ho, four equivalent Mn, and one Ge atom. The Ge–Ge bond length is 2.57 Å.
