Title: Materials Data on Ce3Th3O11 by Materials Project

Abstract

Th3Ce3O11 crystallizes in the monoclinic Pm space group. The structure is three-dimensional. there are three 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 2.37–2.63 Å. In the second 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 2.39–2.55 Å. In the third 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 2.40–2.49 Å. There are three inequivalent Ce+3.33+ sites. In the first Ce+3.33+ site, Ce+3.33+ is bonded to seven O2- atoms to form a mixture of distorted edge and corner-sharing CeO7 hexagonal pyramids. There are a spread of Ce–O bond distances ranging from 2.35–2.47 Å. In the second Ce+3.33+ site, Ce+3.33+ is bonded to seven O2- atoms to form a mixture of distorted edge and corner-sharing CeO7 hexagonal pyramids. There are a spread of Ce–O bond distances ranging from 2.35–2.49 Å. In the third Ce+3.33+ site, Ce+3.33+ is bonded in a 6-coordinate geometry to six O2- atoms. Theremore » are a spread of Ce–O bond distances ranging from 2.29–2.41 Å. There are eleven inequivalent O2- sites. In the first O2- site, O2- is bonded to three Th4+ and one Ce+3.33+ atom to form OCeTh3 tetrahedra that share corners with fifteen OCeTh3 tetrahedra and edges with six OCe2Th2 tetrahedra. In the second O2- site, O2- is bonded to one Th4+ and three Ce+3.33+ atoms to form a mixture of edge and corner-sharing OCe3Th tetrahedra. In the third O2- site, O2- is bonded to two equivalent Th4+ and two Ce+3.33+ atoms to form OCe2Th2 tetrahedra that share corners with sixteen OCeTh3 tetrahedra and edges with five OCe2Th2 tetrahedra. In the fourth O2- site, O2- is bonded to two Th4+ and two equivalent Ce+3.33+ atoms to form OCe2Th2 tetrahedra that share corners with fourteen OCe3Th tetrahedra and edges with six OCe2Th2 tetrahedra. In the fifth O2- site, O2- is bonded to one Th4+ and three Ce+3.33+ atoms to form distorted OCe3Th tetrahedra that share corners with sixteen OCeTh3 tetrahedra and edges with four OCe2Th2 tetrahedra. In the sixth O2- site, O2- is bonded to three Th4+ and one Ce+3.33+ atom to form OCeTh3 tetrahedra that share corners with fifteen OCe3Th tetrahedra and edges with six OCe2Th2 tetrahedra. In the seventh O2- site, O2- is bonded to four Th4+ atoms to form OTh4 tetrahedra that share corners with sixteen OCeTh3 tetrahedra and edges with six OCe2Th2 tetrahedra. In the eighth O2- site, O2- is bonded to three Th4+ and one Ce+3.33+ atom to form OCeTh3 tetrahedra that share corners with fifteen OCeTh3 tetrahedra and edges with six OCe3Th tetrahedra. In the ninth O2- site, O2- is bonded to one Th4+ and three Ce+3.33+ atoms to form distorted OCe3Th tetrahedra that share corners with sixteen OCeTh3 tetrahedra and edges with four OCe3Th tetrahedra. In the tenth O2- site, O2- is bonded to three Th4+ and one Ce+3.33+ atom to form a mixture of edge and corner-sharing OCeTh3 tetrahedra. In the eleventh O2- site, O2- is bonded to one Th4+ and three Ce+3.33+ atoms to form a mixture of edge and corner-sharing OCe3Th tetrahedra.« less
