Sr2TmReO6 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 Tm(1)O6 octahedra, and faces with four equivalent Re(1)O6 octahedra. Tm(1) is bonded to six equivalent O(1) atoms to form TmO6 octahedra that share corners with six equivalent Re(1)O6 octahedra and faces with eight equivalent Sr(1)O12 cuboctahedra. The corner-sharing octahedra are not tilted. Re(1) is bonded to six equivalent O(1) atoms to form ReO6 octahedra that share corners with six equivalent Tm(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 Tm(1), and one Re(1) atom.
