Materials Data on Ba4Sr(SnO3)5 by Materials Project
Ba4Sr(SnO3)5 is (Cubic) Perovskite-derived structured and crystallizes in the trigonal R-3m space group. The structure is three-dimensional. there are two inequivalent Ba2+ sites. In the first Ba2+ site, Ba2+ is bonded to twelve O2- atoms to form BaO12 cuboctahedra that share corners with twelve BaO12 cuboctahedra, faces with three equivalent BaO12 cuboctahedra, faces with three equivalent SrO12 cuboctahedra, and faces with eight SnO6 octahedra. There are nine shorter (2.95 Å) and three longer (2.96 Å) Ba–O bond lengths. In the second Ba2+ site, Ba2+ is bonded to twelve O2- atoms to form BaO12 cuboctahedra that share corners with three equivalent SrO12 cuboctahedra, corners with nine BaO12 cuboctahedra, faces with six BaO12 cuboctahedra, and faces with eight SnO6 octahedra. There are nine shorter (2.95 Å) and three longer (2.97 Å) Ba–O bond lengths. Sr2+ is bonded to twelve O2- atoms to form SrO12 cuboctahedra that share corners with six equivalent BaO12 cuboctahedra, corners with six equivalent SrO12 cuboctahedra, faces with six equivalent BaO12 cuboctahedra, and faces with eight SnO6 octahedra. There are six shorter (2.93 Å) and six longer (2.95 Å) Sr–O bond lengths. There are three inequivalent Sn4+ sites. In the first Sn4+ site, Sn4+ is bonded to six O2- atoms to form SnO6 octahedra that share corners with six SnO6 octahedra, faces with three equivalent SrO12 cuboctahedra, and faces with five BaO12 cuboctahedra. The corner-sharing octahedra tilt angles range from 0–1°. There are three shorter (2.08 Å) and three longer (2.09 Å) Sn–O bond lengths. In the second Sn4+ site, Sn4+ is bonded to six equivalent O2- atoms to form SnO6 octahedra that share corners with six equivalent SnO6 octahedra and faces with eight BaO12 cuboctahedra. The corner-sharing octahedral tilt angles are 0°. All Sn–O bond lengths are 2.09 Å. In the third Sn4+ site, Sn4+ is bonded to six O2- atoms to form SnO6 octahedra that share corners with six SnO6 octahedra, a faceface with one SrO12 cuboctahedra, and faces with seven BaO12 cuboctahedra. The corner-sharing octahedra tilt angles range from 0–1°. All Sn–O bond lengths are 2.09 Å. There are three inequivalent O2- sites. In the first O2- site, O2- is bonded in a distorted linear geometry to three Ba2+, one Sr2+, and two Sn4+ atoms. In the second O2- site, O2- is bonded in a distorted linear geometry to two equivalent Ba2+, two equivalent Sr2+, and two equivalent Sn4+ atoms. In the third O2- site, O2- is bonded in a distorted linear geometry to four Ba2+ and two Sn4+ atoms.
