Materials Data on Tb5Ge3C by Materials Project
Tb5Ge3C crystallizes in the hexagonal P6_3/mcm space group. The structure is three-dimensional. there are two inequivalent Tb sites. In the first Tb site, Tb is bonded in a 6-coordinate geometry to six equivalent Ge atoms. All Tb–Ge bond lengths are 3.06 Å. In the second Tb site, Tb is bonded in a 2-coordinate geometry to five equivalent Ge and two equivalent C atoms. There are a spread of Tb–Ge bond distances ranging from 3.03–3.62 Å. Both Tb–C bond lengths are 2.50 Å. Ge is bonded in a 9-coordinate geometry to nine Tb atoms. C is bonded to six equivalent Tb atoms to form face-sharing CTb6 octahedra.
