Materials Data on CeTh3O8 by Materials Project
Th3CeO8 is Fluorite-derived structured and crystallizes in the trigonal R-3m space group. The structure is three-dimensional. there are two inequivalent Th4+ sites. In the first Th4+ site, Th4+ is bonded in a body-centered cubic geometry to eight O2- atoms. There are a spread of Th–O bond distances ranging from 2.41–2.45 Å. In the second Th4+ site, Th4+ is bonded in a body-centered cubic geometry to eight O2- atoms. There are six shorter (2.42 Å) and two longer (2.45 Å) Th–O bond lengths. Ce4+ is bonded in a body-centered cubic geometry to eight O2- atoms. There are two shorter (2.36 Å) and six longer (2.41 Å) Ce–O bond lengths. There are four inequivalent O2- sites. In the first O2- site, O2- is bonded to four Th4+ atoms to form a mixture of corner and edge-sharing OTh4 tetrahedra. In the second O2- site, O2- is bonded to three equivalent Th4+ and one Ce4+ atom to form OCeTh3 tetrahedra that share corners with sixteen OTh4 tetrahedra and edges with six OCe3Th tetrahedra. In the third O2- site, O2- is bonded to one Th4+ and three equivalent Ce4+ atoms to form OCe3Th tetrahedra that share corners with sixteen OTh4 tetrahedra and edges with six OCeTh3 tetrahedra. In the fourth O2- site, O2- is bonded to four Th4+ atoms to form a mixture of corner and edge-sharing OTh4 tetrahedra.
