Abstract

SrLa2Ti3O9 is (Cubic) Perovskite-derived structured and crystallizes in the trigonal P-3m1 space group. The structure is three-dimensional. Sr2+ is bonded to twelve O2- atoms to form SrO12 cuboctahedra that share corners with six equivalent SrO12 cuboctahedra, corners with six equivalent LaO12 cuboctahedra, faces with six equivalent LaO12 cuboctahedra, and faces with eight TiO6 octahedra. There are six shorter (2.79 Å) and six longer (2.81 Å) Sr–O bond lengths. La3+ is bonded to twelve O2- atoms to form LaO12 cuboctahedra that share corners with three equivalent SrO12 cuboctahedra, corners with nine equivalent LaO12 cuboctahedra, faces with three equivalent SrO12 cuboctahedra, faces with three equivalent LaO12 cuboctahedra, and faces with eight TiO6 octahedra. There are six shorter (2.78 Å) and six longer (2.79 Å) La–O bond lengths. There are two inequivalent Ti+3.33+ sites. In the first Ti+3.33+ site, Ti+3.33+ is bonded to six equivalent O2- atoms to form TiO6 octahedra that share corners with six equivalent TiO6 octahedra, faces with two equivalent SrO12 cuboctahedra, and faces with six equivalent LaO12 cuboctahedra. The corner-sharing octahedral tilt angles are 2°. All Ti–O bond lengths are 1.97 Å. In the second Ti+3.33+ site, Ti+3.33+ is bonded to six O2- atoms to form TiO6 octahedra thatmore »« less
