The structure described by BaTbO3 is Orthorhombic Perovskite-like structured and crystallizes in the orthorhombic Imma space group. Ba(1) is bonded in a 7-coordinate geometry to three equivalent O(2) and four equivalent O(1) 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 22-26°. 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 5-coordinate geometry to three equivalent Ba(1) and two equivalent Tb(1) atoms. is represented by the CIF file [CIF]
