Abstract

Sr3Zr2Nb2O12 crystallizes in the trigonal R-3m 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 equivalent SrO12 cuboctahedra, faces with three equivalent SrO12 cuboctahedra, faces with four equivalent ZrO6 octahedra, and faces with four equivalent NbO6 octahedra. There are three shorter (2.86 Å) and nine longer (2.92 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 six equivalent SrO12 cuboctahedra, faces with six equivalent SrO12 cuboctahedra, faces with two equivalent NbO6 octahedra, and faces with six equivalent ZrO6 octahedra. There are six shorter (2.83 Å) and six longer (2.92 Å) Sr–O bond lengths. Zr4+ is bonded to six O2- atoms to form ZrO6 octahedra that share corners with three equivalent ZrO6 octahedra, corners with three equivalent NbO6 octahedra, and faces with seven SrO12 cuboctahedra. The corner-sharing octahedra tilt angles range from 0–6°. All Zr–O bond lengths are 2.10 Å. Nb5+ is bonded to six O2- atoms to form NbO6 octahedra that share corners with three equivalent ZrO6 octahedra, corners with threemore »« less
