The compound described by Sr2LuTaO6 is (Cubic) Perovskite-derived structured and crystallizes in the cubic Fm-3m space group. Sr(1) is bonded to twelve equivalent O(1) atoms to form SrO12 cuboctahedra that share corners with twelve equivalent Sr(1)O12 cuboctahedra, faces with six equivalent Sr(1)O12 cuboctahedra, faces with four equivalent Lu(1)O6 octahedra, and faces with four equivalent Ta(1)O6 octahedra. Lu(1) is bonded to six equivalent O(1) atoms to form LuO6 octahedra that share corners with six equivalent Ta(1)O6 octahedra and faces with eight equivalent Sr(1)O12 cuboctahedra. The corner-sharing octahedra are not tilted. Ta(1) is bonded to six equivalent O(1) atoms to form TaO6 octahedra that share corners with six equivalent Lu(1)O6 octahedra and faces with eight equivalent Sr(1)O12 cuboctahedra. The corner-sharing octahedra are not tilted. O(1) is bonded in a distorted linear geometry to four equivalent Sr(1), one Lu(1), and one Ta(1) atom. is represented by the Crystallographic Information File (CIF) [CIF]
