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 2.37–2.53 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 2.36–2.55 Å. There are three inequivalent Ce+3.33+ sites. In the first Ce+3.33+ site, Ce+3.33+ is bonded in a 7-coordinate geometry to seven O2- atoms. There are a spread of Ce–O bond distances ranging from 2.33–2.51 Å. In the second Ce+3.33+ site, Ce+3.33+ is bonded in a distorted hexagonal planar geometry to six O2- atoms. There are a spread of Ce–O bond distances ranging from 2.31–2.37 Å. In the third Ce+3.33+ site, Ce+3.33+ is bonded in a 7-coordinate geometry to seven O2- atoms. There are a spread of Ce–O bond distances ranging from 2.33–2.50 Å. There are nine inequivalent O2- sites. In the first O2- site, O2- is bonded to one Th4+ and three Ce+3.33+ atoms to form a mixture of distorted edge and corner-sharing OCe3Th tetrahedra.more »« less
