BaCeO3 crystallizes in the trigonal R-3c 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 corner-sharing CeO6 octahedra. The corner-sharing octahedral tilt angles are 22°. O(1) is bonded in a 5-coordinate geometry to three equivalent Ba(1) and two equivalent Ce(1) atoms.
BaCeO3 crystallizes in the trigonal R-3c space group. Ba(1) is bonded in a 9-coordinate geometry to nine equivalent O(1) atoms. There are three shorter (2.72 Å) and six longer (3.13 Å) Ba(1)-O(1) bond lengths. Ce(1) is bonded to six equivalent O(1) atoms to form corner-sharing CeO6 octahedra. The corner-sharing octahedral tilt angles are 22°. All Ce(1)-O(1) bond lengths are 2.25 Å. O(1) is bonded in a 5-coordinate geometry to three equivalent Ba(1) and two equivalent Ce(1) atoms.
