Materials Data on CeYC4 by Materials Project
CeYC4 crystallizes in the monoclinic C2/m space group. The structure is three-dimensional. Ce3+ is bonded in a distorted q4 geometry to ten C+1.50- atoms. There are a spread of Ce–C bond distances ranging from 2.51–2.75 Å. Y3+ is bonded in a 10-coordinate geometry to ten C+1.50- atoms. There are a spread of Y–C bond distances ranging from 2.45–2.72 Å. There are two inequivalent C+1.50- sites. In the first C+1.50- site, C+1.50- is bonded in a 2-coordinate geometry to two equivalent Ce3+, three equivalent Y3+, and one C+1.50- atom. The C–C bond length is 1.30 Å. In the second C+1.50- site, C+1.50- is bonded in a 6-coordinate geometry to three equivalent Ce3+, two equivalent Y3+, and one C+1.50- atom.
