Materials Data on Er5Ge3C by Materials Project

Er5Ge3C crystallizes in the hexagonal P6_3/mcm space group. The structure is three-dimensional. there are two inequivalent Er sites. In the first Er site, Er is bonded in a 6-coordinate geometry to six equivalent Ge atoms. All Er–Ge bond lengths are 3.02 Å. In the second Er site, Er is bonded in a 2-coordinate geometry to five equivalent Ge and two equivalent C atoms. There are a spread of Er–Ge bond distances ranging from 2.98–3.57 Å. Both Er–C bond lengths are 2.46 Å. Ge is bonded in a 9-coordinate geometry to nine Er atoms. C is bonded to six equivalent Er atoms to form face-sharing CEr6 octahedra.
