Materials Data on Tm5Ge3C by Materials Project
Tm5Ge3C crystallizes in the hexagonal P6_3/mcm space group. The structure is three-dimensional. there are two inequivalent Tm sites. In the first Tm site, Tm is bonded in a 6-coordinate geometry to six equivalent Ge atoms. All Tm–Ge bond lengths are 3.01 Å. In the second Tm site, Tm is bonded in a 2-coordinate geometry to five equivalent Ge and two equivalent C atoms. There are a spread of Tm–Ge bond distances ranging from 2.95–3.50 Å. Both Tm–C bond lengths are 2.44 Å. Ge is bonded in a 9-coordinate geometry to nine Tm atoms. C is bonded to six equivalent Tm atoms to form face-sharing CTm6 octahedra.
