BaTbO3 crystallizes in the trigonal R-3c space group. Ba(1) is bonded in a 9-coordinate geometry to nine equivalent O(1) atoms. Tb(1) is bonded to six equivalent O(1) atoms to form corner-sharing TbO6 octahedra. The corner-sharing octahedral tilt angles are 23°. O(1) is bonded in a 5-coordinate geometry to three equivalent Ba(1) and two equivalent Tb(1) atoms.
BaTbO3 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 (2.71 Å) and six longer (3.15 Å) Ba(1)-O(1) bond lengths. Tb(1) is bonded to six equivalent O(1) atoms to form corner-sharing TbO6 octahedra. The corner-sharing octahedral tilt angles are 23°. All Tb(1)-O(1) bond lengths are 2.27 Å. O(1) is bonded in a 5-coordinate geometry to three equivalent Ba(1) and two equivalent Tb(1) atoms.
