Sr6Sn2NF is (Cubic) Perovskite-derived structured and crystallizes in the cubic Fm-3m space group. Sr(1) is bonded in a linear geometry to four equivalent Sn(1), one N(1), and one F(1) atom. Sn(1) is bonded to twelve equivalent Sr(1) atoms to form SnSr12 cuboctahedra that share corners with twelve equivalent Sn(1)Sr12 cuboctahedra, faces with six equivalent Sn(1)Sr12 cuboctahedra, faces with four equivalent N(1)Sr6 octahedra, and faces with four equivalent F(1)Sr6 octahedra. N(1) is bonded to six equivalent Sr(1) atoms to form NSr6 octahedra that share corners with six equivalent F(1)Sr6 octahedra and faces with eight equivalent Sn(1)Sr12 cuboctahedra. The corner-sharing octahedra are not tilted. F(1) is bonded to six equivalent Sr(1) atoms to form FSr6 octahedra that share corners with six equivalent N(1)Sr6 octahedra and faces with eight equivalent Sn(1)Sr12 cuboctahedra. The corner-sharing octahedra are not tilted.
