Materials Data on Lu5Ge3C by Materials Project
Lu5Ge3C crystallizes in the hexagonal P6_3/mcm space group. The structure is three-dimensional. there are two inequivalent Lu sites. In the first Lu site, Lu is bonded in a 6-coordinate geometry to six equivalent Ge atoms. All Lu–Ge bond lengths are 2.97 Å. In the second Lu site, Lu is bonded in a 2-coordinate geometry to five equivalent Ge and two equivalent C atoms. There are a spread of Lu–Ge bond distances ranging from 2.93–3.51 Å. Both Lu–C bond lengths are 2.42 Å. Ge is bonded in a 9-coordinate geometry to nine Lu atoms. C is bonded to six equivalent Lu atoms to form face-sharing CLu6 octahedra.
