The crystal structure described by BaTbEuSbO6 is Orthorhombic Perovskite-derived structured and crystallizes in the orthorhombic Pnnn space group. There are two inequivalent Ba sites. In the first Ba site, Ba(1) is bonded to four equivalent O(1), four equivalent O(2), and four equivalent O(3) atoms to form BaO12 cuboctahedra that share faces with four equivalent Tb(1)O6 octahedra and faces with four equivalent Sb(1)O6 octahedra. In the second Ba site, Ba(2) is bonded in a 8-coordinate geometry to four equivalent O(2) and four equivalent O(3) atoms. Tb(1) is bonded to two equivalent O(1), two equivalent O(2), and two equivalent O(3) atoms to form TbO6 octahedra that share corners with six equivalent Sb(1)O6 octahedra and faces with two equivalent Ba(1)O12 cuboctahedra. The corner-sharing octahedral tilt angles range from 16-21°. There are two inequivalent Eu sites. In the first Eu site, Eu(1) is bonded in a 4-coordinate geometry to four equivalent O(2) atoms. In the second Eu site, Eu(2) is bonded in a 8-coordinate geometry to four equivalent O(1) and four equivalent O(3) atoms. Sb(1) is bonded to two equivalent O(1), two equivalent O(2), and two equivalent O(3) atoms to form SbO6 octahedra that share corners with six equivalent Tb(1)O6 octahedra and faces with two equivalent Ba(1)O12 cuboctahedra. The corner-sharing octahedral tilt angles range from 16-21°. There are three inequivalent O sites. In the first O site, O(1) is bonded in a 3-coordinate geometry to one Ba(1), one Tb(1), one Eu(2), and one Sb(1) atom. In the second O site, O(2) is bonded in a 5-coordinate geometry to one Ba(1), one Ba(2), one Tb(1), one Eu(1), and one Sb(1) atom. In the third O site, O(3) is bonded in a 3-coordinate geometry to one Ba(1), one Ba(2), one Tb(1), one Eu(2), and one Sb(1) atom. is represented by the Crystallographic Information File (CIF) [CIF]
