Title: Materials Data on Ba3ZnSb2O9 by Materials Project

Abstract

Ba3ZnSb2O9 is (Cubic) Perovskite-derived structured and crystallizes in the hexagonal P6_3/mmc 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 nine BaO12 cuboctahedra, corners with three equivalent SbO6 octahedra, faces with seven BaO12 cuboctahedra, faces with three equivalent ZnO6 octahedra, and faces with four equivalent SbO6 octahedra. The corner-sharing octahedral tilt angles are 8°. There are a spread of Ba–O bond distances ranging from 2.97–3.06 Å. In the second Ba2+ site, Ba2+ is bonded to twelve O2- atoms to form BaO12 cuboctahedra that share corners with twelve BaO12 cuboctahedra, faces with six equivalent BaO12 cuboctahedra, faces with two equivalent ZnO6 octahedra, and faces with six equivalent SbO6 octahedra. There are six shorter (2.98 Å) and six longer (2.99 Å) Ba–O bond lengths. Zn2+ is bonded to six equivalent O2- atoms to form ZnO6 octahedra that share corners with six equivalent SbO6 octahedra and faces with eight BaO12 cuboctahedra. The corner-sharing octahedral tilt angles are 5°. All Zn–O bond lengths are 2.14 Å. Sb5+ is bonded to six O2- atoms to form SbO6 octahedra that share corners withmore » three equivalent BaO12 cuboctahedra, corners with three equivalent ZnO6 octahedra, faces with seven BaO12 cuboctahedra, and a faceface with one SbO6 octahedra. The corner-sharing octahedral tilt angles are 5°. There are three shorter (1.96 Å) and three longer (2.10 Å) Sb–O bond lengths. There are two inequivalent O2- sites. In the first O2- site, O2- is bonded in a distorted L-shaped geometry to four Ba2+ and two equivalent Sb5+ atoms. In the second O2- site, O2- is bonded in a distorted linear geometry to four Ba2+, one Zn2+, and one Sb5+ atom.« less
