Materials Data on Tb(MnGe)2 by Materials Project
TbMn2Ge2 crystallizes in the tetragonal I4/mmm space group. The structure is three-dimensional. Tb is bonded in a 8-coordinate geometry to eight equivalent Ge atoms. All Tb–Ge bond lengths are 3.08 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 Tb, four equivalent Mn, and one Ge atom. The Ge–Ge bond length is 2.60 Å.
