BaTbO3 crystallizes in the tetragonal I4/mcm space group. Ba(1) is bonded in a 8-coordinate geometry to four equivalent O(1) and four equivalent O(2) atoms. Tb(1) is bonded to two equivalent O(2) and four equivalent O(1) atoms to form corner-sharing TbO6 octahedra. The corner-sharing octahedral tilt angles range from 0-26°. There are two inequivalent O sites. In the first O site, O(1) is bonded in a 4-coordinate geometry to two equivalent Ba(1) and two equivalent Tb(1) atoms. In the second O site, O(2) is bonded in a distorted linear geometry to four equivalent Ba(1) and two equivalent Tb(1) atoms.
