Materials Data on NaSr2OsO6 by Materials Project
NaSr2OsO6 is (Cubic) Perovskite-derived structured and crystallizes in the cubic Fm-3m space group. The structure is three-dimensional. Na1+ is bonded to six equivalent O2- atoms to form NaO6 octahedra that share corners with six equivalent OsO6 octahedra and faces with eight equivalent SrO12 cuboctahedra. The corner-sharing octahedral tilt angles are 0°. All Na–O bond lengths are 2.20 Å. Sr2+ is bonded to twelve equivalent O2- atoms to form SrO12 cuboctahedra that share corners with twelve equivalent SrO12 cuboctahedra, faces with six equivalent SrO12 cuboctahedra, faces with four equivalent NaO6 octahedra, and faces with four equivalent OsO6 octahedra. All Sr–O bond lengths are 2.90 Å. Os7+ is bonded to six equivalent O2- atoms to form OsO6 octahedra that share corners with six equivalent NaO6 octahedra and faces with eight equivalent SrO12 cuboctahedra. The corner-sharing octahedral tilt angles are 0°. All Os–O bond lengths are 1.90 Å. O2- is bonded in a distorted linear geometry to one Na1+, four equivalent Sr2+, and one Os7+ atom.
