Materials Data on CePr2O6 by Materials Project

Pr2CeO6 is Fluorite-derived structured and crystallizes in the tetragonal I4/mmm 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 (2.50 Å) Pr–O bond lengths. Ce4+ is bonded in a body-centered cubic geometry to eight equivalent O2- atoms. All Ce–O bond lengths are 2.38 Å. There are two inequivalent O2- sites. In the first 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. In the second O2- site, O2- is bonded to four equivalent Pr4+ atoms to form a mixture of corner and edge-sharing OPr4 tetrahedra.
