Abstract

Sr3(ZnTa2)O9 is (Cubic) Perovskite-derived structured and crystallizes in the trigonal P-3m1 space group. The structure is three-dimensional. there are two inequivalent Sr2+ sites. In the first Sr2+ site, Sr2+ is bonded to twelve O2- atoms to form SrO12 cuboctahedra that share corners with twelve SrO12 cuboctahedra, faces with six equivalent SrO12 cuboctahedra, faces with two equivalent ZnO6 octahedra, and faces with six equivalent TaO6 octahedra. There are six shorter (2.84 Å) and six longer (2.86 Å) Sr–O bond lengths. In the second Sr2+ site, Sr2+ is bonded to twelve O2- atoms to form SrO12 cuboctahedra that share corners with twelve SrO12 cuboctahedra, faces with six SrO12 cuboctahedra, faces with three equivalent ZnO6 octahedra, and faces with five equivalent TaO6 octahedra. There are a spread of Sr–O bond distances ranging from 2.86–2.91 Å. Ta5+ is bonded to six O2- atoms to form TaO6 octahedra that share corners with three equivalent TaO6 octahedra, corners with three equivalent ZnO6 octahedra, and faces with eight SrO12 cuboctahedra. The corner-sharing octahedra tilt angles range from 0–4°. There are three shorter (1.93 Å) and three longer (2.07 Å) Ta–O bond lengths. Zn2+ is bonded to six equivalent O2- atoms to form ZnO6 octahedra that share cornersmore »« less
