Materials Data on Ce2PrO6 by Materials Project
PrCe2O6 is Fluorite-derived structured and crystallizes in the orthorhombic Immm space group. The structure is three-dimensional. Pr4+ is bonded in a body-centered cubic geometry to eight O2- atoms. There are four shorter (2.45 Å) and four longer (2.47 Å) Pr–O bond lengths. Ce4+ is bonded in a body-centered cubic geometry to eight O2- atoms. There are four shorter (2.37 Å) and four longer (2.38 Å) Ce–O bond lengths. There are two inequivalent O2- sites. In the first O2- site, O2- is bonded to one Pr4+ and three equivalent Ce4+ atoms to form a mixture of corner and edge-sharing OCe3Pr tetrahedra. In the second O2- site, O2- is bonded to two equivalent Pr4+ and two equivalent Ce4+ atoms to form a mixture of corner and edge-sharing OCe2Pr2 tetrahedra.
