Materials Data on CePrO4 by Materials Project
PrCeO4 is Fluorite-derived structured and crystallizes in the tetragonal P4/mmm space group. The structure is three-dimensional. Pr4+ is bonded in a body-centered cubic geometry to eight equivalent O2- atoms. All Pr–O bond lengths are 2.47 Å. Ce4+ is bonded in a body-centered cubic geometry to eight equivalent O2- atoms. All Ce–O bond lengths are 2.38 Å. O2- is bonded to two equivalent Pr4+ and two equivalent Ce4+ atoms to form a mixture of edge and corner-sharing OCe2Pr2 tetrahedra.
