Materials Data on SrLaNbZnO6 by Materials Project

Abstract

LaSrZnNbO6 is (Cubic) Perovskite-derived structured and crystallizes in the cubic F-43m space group. The structure is three-dimensional. Sr2+ is bonded to twelve equivalent O2- atoms to form SrO12 cuboctahedra that share corners with twelve equivalent SrO12 cuboctahedra, faces with six equivalent LaO12 cuboctahedra, faces with four equivalent NbO6 octahedra, and faces with four equivalent ZnO6 octahedra. All Sr–O bond lengths are 2.86 Å. La3+ is bonded to twelve equivalent O2- atoms to form LaO12 cuboctahedra that share corners with twelve equivalent LaO12 cuboctahedra, faces with six equivalent SrO12 cuboctahedra, faces with four equivalent NbO6 octahedra, and faces with four equivalent ZnO6 octahedra. All La–O bond lengths are 2.86 Å. Nb5+ is bonded to six equivalent O2- atoms to form NbO6 octahedra that share corners with six equivalent ZnO6 octahedra, faces with four equivalent SrO12 cuboctahedra, and faces with four equivalent LaO12 cuboctahedra. The corner-sharing octahedral tilt angles are 0°. All Nb–O bond lengths are 1.99 Å. Zn2+ is bonded to six equivalent O2- atoms to form ZnO6 octahedra that share corners with six equivalent NbO6 octahedra, faces with four equivalent SrO12 cuboctahedra, and faces with four equivalent LaO12 cuboctahedra. The corner-sharing octahedral tilt angles are 0°. All Zn–O bond lengths are 2.05 Å. O2- is bonded in a distorted linear geometry to two equivalent Sr2+, two equivalent La3+, one Nb5+, and one Zn2+ atom.
