Materials Data on CeRhC2 by Materials Project

CeRhC2 crystallizes in the tetragonal P4_3 space group. The structure is three-dimensional. Ce3+ is bonded in a 8-coordinate geometry to eight C3- atoms. There are a spread of Ce–C bond distances ranging from 2.75–2.93 Å. Rh3+ is bonded in a 4-coordinate geometry to four C3- atoms. There are a spread of Rh–C bond distances ranging from 2.03–2.15 Å. There are two inequivalent C3- sites. In the first C3- site, C3- is bonded in a 7-coordinate geometry to four equivalent Ce3+, two equivalent Rh3+, and one C3- atom. The C–C bond length is 1.37 Å. In the second C3- site, C3- is bonded in a 7-coordinate geometry to four equivalent Ce3+, two equivalent Rh3+, and one C3- atom.
