Materials Data on CePO4 by Materials Project

Abstract

CePO4 is Zircon-like structured and crystallizes in the hexagonal P6_422 space group. The structure is three-dimensional. Ce3+ is bonded to eight equivalent O2- atoms to form distorted CeO8 hexagonal bipyramids that share corners with four equivalent PO4 tetrahedra, edges with four equivalent CeO8 hexagonal bipyramids, and edges with two equivalent PO4 tetrahedra. There are four shorter (2.44 Å) and four longer (2.60 Å) Ce–O bond lengths. P5+ is bonded to four equivalent O2- atoms to form PO4 tetrahedra that share corners with four equivalent CeO8 hexagonal bipyramids and edges with two equivalent CeO8 hexagonal bipyramids. All P–O bond lengths are 1.55 Å. O2- is bonded in a 1-coordinate geometry to two equivalent Ce3+ and one P5+ atom.
