Materials Data on Tb2InGe2 by Materials Project
Tb2InGe2 crystallizes in the tetragonal P4/mbm space group. The structure is three-dimensional. Tb is bonded in a 6-coordinate geometry to four equivalent In and six equivalent Ge atoms. All Tb–In bond lengths are 3.46 Å. There are two shorter (2.98 Å) and four longer (3.10 Å) Tb–Ge bond lengths. In is bonded to eight equivalent Tb and four equivalent Ge atoms to form a mixture of corner and face-sharing InTb8Ge4 cuboctahedra. All In–Ge bond lengths are 2.96 Å. Ge is bonded in a 9-coordinate geometry to six equivalent Tb, two equivalent In, and one Ge atom. The Ge–Ge bond length is 2.56 Å.
