The material described by Ba2TbWO6 is (Cubic) Perovskite-derived structured and crystallizes in the monoclinic C2/m space group. Ba(1) is bonded to four equivalent O(1) and eight equivalent O(2) atoms to form BaO12 cuboctahedra that share corners with twelve equivalent Ba(1)O12 cuboctahedra, faces with six equivalent Ba(1)O12 cuboctahedra, faces with four equivalent Tb(1)O6 octahedra, and faces with four equivalent W(1)O6 octahedra. Tb(1) is bonded to two equivalent O(1) and four equivalent O(2) atoms to form TbO6 octahedra that share corners with six equivalent W(1)O6 octahedra and faces with eight equivalent Ba(1)O12 cuboctahedra. The corner-sharing octahedral tilt angles are 1°. W(1) is bonded to two equivalent O(1) and four equivalent O(2) atoms to form WO6 octahedra that share corners with six equivalent Tb(1)O6 octahedra and faces with eight equivalent Ba(1)O12 cuboctahedra. The corner-sharing octahedral tilt angles are 1°. There are two inequivalent O sites. In the first O site, O(1) is bonded to four equivalent Ba(1), one Tb(1), and one W(1) atom to form a mixture of distorted edge and corner-sharing OBa4TbW octahedra. The corner-sharing octahedral tilt angles range from 0-5°. In the second O site, O(2) is bonded in a distorted linear geometry to four equivalent Ba(1), one Tb(1), and one W(1) atom. is represented by the Crystallographic Information File (CIF) [CIF]
