Materials Data on Ce3Dy2O9 by Materials Project
Abstract
Dy2Ce3O9 crystallizes in the triclinic P1 space group. The structure is three-dimensional. there are two inequivalent Dy3+ sites. In the first Dy3+ site, Dy3+ is bonded in a 6-coordinate geometry to six O2- atoms. There are a spread of Dy–O bond distances ranging from 2.16–2.45 Å. In the second Dy3+ site, Dy3+ is bonded in a 6-coordinate geometry to six O2- atoms. There are a spread of Dy–O bond distances ranging from 2.16–2.47 Å. There are three inequivalent Ce4+ sites. In the first Ce4+ site, Ce4+ is bonded in a body-centered cubic geometry to eight O2- atoms. There are a spread of Ce–O bond distances ranging from 2.28–2.49 Å. In the second Ce4+ site, Ce4+ is bonded in a body-centered cubic geometry to eight O2- atoms. There are a spread of Ce–O bond distances ranging from 2.27–2.50 Å. In the third Ce4+ site, Ce4+ is bonded in a body-centered cubic geometry to eight O2- atoms. There are a spread of Ce–O bond distances ranging from 2.30–2.44 Å. There are nine inequivalent O2- sites. In the first O2- site, O2- is bonded to two equivalent Dy3+ and two equivalent Ce4+ atoms to form a mixture of corner and edge-sharing OCe2Dy2 tetrahedra.more »
