LiBaTbSbO6 crystallizes in the orthorhombic Pnnn space group. The structure consists of four 7439-93-2 atoms inside a BaTbSbO6 framework. In the BaTbSbO6 framework, 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 corners with four equivalent Ba(2)O12 cuboctahedra, faces with two equivalent Ba(2)O12 cuboctahedra, 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 to four equivalent O(1), four equivalent O(2), and four equivalent O(3) atoms to form BaO12 cuboctahedra that share corners with four equivalent Ba(1)O12 cuboctahedra, faces with two equivalent Ba(1)O12 cuboctahedra, faces with four equivalent Tb(1)O6 octahedra, and faces with four equivalent Sb(1)O6 octahedra. 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, faces with two equivalent Ba(1)O12 cuboctahedra, and faces with two equivalent Ba(2)O12 cuboctahedra. The corner-sharing octahedral tilt angles range from 7-9°. 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, faces with two equivalent Ba(1)O12 cuboctahedra, and faces with two equivalent Ba(2)O12 cuboctahedra. The corner-sharing octahedral tilt angles range from 7-9°. There are three inequivalent O sites. In the first O site, O(1) is bonded in a distorted rectangular see-saw-like geometry to one Ba(1), one Ba(2), one Tb(1), and one Sb(1) atom. In the second O site, O(2) is bonded in a distorted linear geometry to one Ba(1), one Ba(2), one Tb(1), and one Sb(1) atom. In the third O site, O(3) is bonded in a distorted linear geometry to one Ba(1), one Ba(2), one Tb(1), and one Sb(1) atom.
