The material described by Ba2CePbO6 crystallizes in the trigonal R-3 space group. Ba(1) is bonded in a 9-coordinate geometry to nine equivalent O(1) atoms. Ce(1) is bonded to six equivalent O(1) atoms to form CeO6 octahedra that share corners with six equivalent Pb(1)O6 octahedra. The corner-sharing octahedral tilt angles are 16°. Pb(1) is bonded to six equivalent O(1) atoms to form PbO6 octahedra that share corners with six equivalent Ce(1)O6 octahedra. The corner-sharing octahedral tilt angles are 16°. O(1) is bonded in a 5-coordinate geometry to three equivalent Ba(1), one Ce(1), and one Pb(1) atom. is represented by the CIF file [CIF]
