LiBa2TbSnO6 crystallizes in the orthorhombic Immm space group. Li(1) is bonded in a square co-planar geometry to two equivalent Ba(1) and four equivalent O(1) atoms. Ba(1) is bonded in a 9-coordinate geometry to one Li(1), 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 TbO6 octahedra that share corners with six equivalent Sn(1)O6 octahedra. The corner-sharing octahedral tilt angles range from 0-4°. Sn(1) is bonded to two equivalent O(2) and four equivalent O(1) atoms to form SnO6 octahedra that share corners with six equivalent Tb(1)O6 octahedra. The corner-sharing octahedral tilt angles range from 0-4°. There are two inequivalent O sites. In the first O site, O(1) is bonded in a distorted T-shaped geometry to one Li(1), two equivalent Ba(1), one Tb(1), and one Sn(1) atom. In the second O site, O(2) is bonded to four equivalent Ba(1), one Tb(1), and one Sn(1) atom to form a mixture of distorted edge and corner-sharing OBa4TbSn octahedra. The corner-sharing octahedral tilt angles range from 0-17°.
