Materials Data on CePbO3 by Materials Project
CePbO3 crystallizes in the monoclinic P2_1/m space group. The structure is three-dimensional. there are two inequivalent Ce4+ sites. In the first Ce4+ site, Ce4+ is bonded in a 6-coordinate geometry to six O2- atoms. There are a spread of Ce–O bond distances ranging from 2.25–2.43 Å. In the second Ce4+ site, Ce4+ is bonded in a 6-coordinate geometry to six O2- atoms. There are a spread of Ce–O bond distances ranging from 2.09–2.65 Å. There are two inequivalent Pb2+ sites. In the first Pb2+ site, Pb2+ is bonded in a 6-coordinate geometry to six O2- atoms. There are a spread of Pb–O bond distances ranging from 2.36–2.85 Å. In the second Pb2+ site, Pb2+ is bonded in a 6-coordinate geometry to six O2- atoms. There are a spread of Pb–O bond distances ranging from 2.36–2.85 Å. There are four inequivalent O2- sites. In the first O2- site, O2- is bonded to two equivalent Ce4+ and two Pb2+ atoms to form a mixture of distorted edge and corner-sharing OCe2Pb2 tetrahedra. In the second O2- site, O2- is bonded to two Ce4+ and two equivalent Pb2+ atoms to form a mixture of edge and corner-sharing OCe2Pb2 tetrahedra. In the third O2- site, O2- is bonded to two Ce4+ and two equivalent Pb2+ atoms to form a mixture of edge and corner-sharing OCe2Pb2 tetrahedra. In the fourth O2- site, O2- is bonded in a distorted single-bond geometry to two equivalent Ce4+ and two Pb2+ atoms.
