Materials Data on Ce2U3O10 by Materials Project
U3Ce2O10 is Fluorite-derived structured and crystallizes in the triclinic P1 space group. The structure is three-dimensional. there are three inequivalent U+4.67+ sites. In the first U+4.67+ site, U+4.67+ is bonded in a body-centered cubic geometry to eight O2- atoms. There are a spread of U–O bond distances ranging from 2.31–2.35 Å. In the second U+4.67+ site, U+4.67+ is bonded in a body-centered cubic geometry to eight O2- atoms. There are a spread of U–O bond distances ranging from 2.29–2.36 Å. In the third U+4.67+ site, U+4.67+ is bonded in a body-centered cubic geometry to eight O2- atoms. There are a spread of U–O bond distances ranging from 2.31–2.35 Å. There are two inequivalent Ce3+ sites. In the first Ce3+ site, Ce3+ is bonded in a body-centered cubic geometry to eight O2- atoms. There are a spread of Ce–O bond distances ranging from 2.38–2.41 Å. In the second Ce3+ site, Ce3+ is bonded in a body-centered cubic geometry to eight O2- atoms. There are a spread of Ce–O bond distances ranging from 2.39–2.41 Å. There are ten inequivalent O2- sites. In the first O2- site, O2- is bonded to two U+4.67+ and two Ce3+ atoms to form OCe2U2 tetrahedra that share corners with sixteen OCeU3 tetrahedra and edges with six OCe2U2 tetrahedra. In the second O2- site, O2- is bonded to two U+4.67+ and two Ce3+ atoms to form OCe2U2 tetrahedra that share corners with sixteen OCeU3 tetrahedra and edges with six OCe2U2 tetrahedra. In the third O2- site, O2- is bonded to three U+4.67+ and one Ce3+ atom to form a mixture of edge and corner-sharing OCeU3 tetrahedra. In the fourth O2- site, O2- is bonded to three U+4.67+ and one Ce3+ atom to form a mixture of edge and corner-sharing OCeU3 tetrahedra. In the fifth O2- site, O2- is bonded to two U+4.67+ and two Ce3+ atoms to form a mixture of edge and corner-sharing OCe2U2 tetrahedra. In the sixth O2- site, O2- is bonded to two U+4.67+ and two Ce3+ atoms to form a mixture of edge and corner-sharing OCe2U2 tetrahedra. In the seventh O2- site, O2- is bonded to two U+4.67+ and two Ce3+ atoms to form a mixture of edge and corner-sharing OCe2U2 tetrahedra. In the eighth O2- site, O2- is bonded to two U+4.67+ and two Ce3+ atoms to form a mixture of edge and corner-sharing OCe2U2 tetrahedra. In the ninth O2- site, O2- is bonded to three U+4.67+ and one Ce3+ atom to form a mixture of edge and corner-sharing OCeU3 tetrahedra. In the tenth O2- site, O2- is bonded to three U+4.67+ and one Ce3+ atom to form a mixture of edge and corner-sharing OCeU3 tetrahedra.
