Ba2CoWO6 is (Cubic) Perovskite-derived structured and crystallizes in the tetragonal I4/mmm space group. Ba(1) is bonded to four equivalent O(2) and eight equivalent O(1) 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 W(1)O6 octahedra, and faces with four equivalent Co(1)O6 octahedra. W(1) is bonded to two equivalent O(2) and four equivalent O(1) atoms to form WO6 octahedra that share corners with six equivalent Co(1)O6 octahedra and faces with eight equivalent Ba(1)O12 cuboctahedra. The corner-sharing octahedra are not tilted. Co(1) is bonded to two equivalent O(2) and four equivalent O(1) atoms to form CoO6 octahedra that share corners with six equivalent W(1)O6 octahedra and faces with eight equivalent Ba(1)O12 cuboctahedra. The corner-sharing octahedra are not tilted. There are two inequivalent O sites. In the first O site, O(1) is bonded to four equivalent Ba(1), one W(1), and one Co(1) atom to form a mixture of distorted edge, face, and corner-sharing OBa4CoW octahedra. The corner-sharing octahedral tilt angles range from 0-62°. In the second O site, O(2) is bonded to four equivalent Ba(1), one W(1), and one Co(1) atom to form a mixture of distorted edge, face, and corner-sharing OBa4CoW octahedra. The corner-sharing octahedral tilt angles range from 0-62°.
