Materials Data on Ba3SrZn2(WO6)2 by Materials Project

Abstract

Ba3SrZn2(WO6)2 is (Cubic) Perovskite-derived structured and crystallizes in the trigonal R3m space group. The structure is three-dimensional. there are three inequivalent Ba2+ sites. In the first Ba2+ site, Ba2+ is bonded to twelve O2- atoms to form BaO12 cuboctahedra that share corners with six equivalent BaO12 cuboctahedra, corners with six equivalent SrO12 cuboctahedra, faces with six BaO12 cuboctahedra, faces with four WO6 octahedra, and faces with four ZnO6 octahedra. There are six shorter (2.91 Å) and six longer (2.93 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 twelve BaO12 cuboctahedra, faces with three equivalent BaO12 cuboctahedra, faces with three equivalent SrO12 cuboctahedra, faces with four WO6 octahedra, and faces with four ZnO6 octahedra. There are three shorter (2.90 Å) and nine longer (2.91 Å) Ba–O bond lengths. In the third 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, faces with four WO6 octahedra, and faces with four ZnO6 octahedra. There are three shorter (2.90 Å) and nine longer (2.91 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 BaO12 cuboctahedra, faces with four WO6 octahedra, and faces with four ZnO6 octahedra. There are six shorter (2.89 Å) and six longer (2.91 Å) Sr–O bond lengths. There are two inequivalent W6+ sites. In the first W6+ site, W6+ is bonded to six O2- atoms to form WO6 octahedra that share corners with six ZnO6 octahedra, faces with three equivalent SrO12 cuboctahedra, and faces with five BaO12 cuboctahedra. The corner-sharing octahedra tilt angles range from 0–1°. All W–O bond lengths are 1.96 Å. In the second W6+ site, W6+ is bonded to six O2- atoms to form WO6 octahedra that share corners with six ZnO6 octahedra, a faceface with one SrO12 cuboctahedra, and faces with seven BaO12 cuboctahedra. The corner-sharing octahedra tilt angles range from 0–1°. All W–O bond lengths are 1.96 Å. There are two inequivalent Zn2+ sites. In the first Zn2+ site, Zn2+ is bonded to six O2- atoms to form ZnO6 octahedra that share corners with six WO6 octahedra, faces with three equivalent SrO12 cuboctahedra, and faces with five BaO12 cuboctahedra. The corner-sharing octahedra tilt angles range from 0–1°. All Zn–O bond lengths are 2.14 Å. In the second Zn2+ site, Zn2+ is bonded to six O2- atoms to form ZnO6 octahedra that share corners with six WO6 octahedra, a faceface with one SrO12 cuboctahedra, and faces with seven BaO12 cuboctahedra. The corner-sharing octahedra tilt angles range from 0–1°. All Zn–O bond lengths are 2.15 Å. There are four inequivalent O2- sites. In the first O2- site, O2- is bonded in a distorted linear geometry to two Ba2+, two equivalent Sr2+, one W6+, and one Zn2+ atom. In the second O2- site, O2- is bonded in a distorted linear geometry to four Ba2+, one W6+, and one Zn2+ atom. In the third O2- site, O2- is bonded in a distorted linear geometry to three Ba2+, one Sr2+, one W6+, and one Zn2+ atom. In the fourth O2- site, O2- is bonded in a distorted linear geometry to three Ba2+, one Sr2+, one W6+, and one Zn2+ atom.
