Abstract

Ba2Ti13O22 crystallizes in the orthorhombic Cmce space group. The structure is three-dimensional. Ba2+ is bonded to twelve O2- atoms to form BaO12 cuboctahedra that share corners with fourteen TiO6 octahedra, edges with three TiO6 octahedra, a faceface with one BaO12 cuboctahedra, and faces with seven TiO6 octahedra. The corner-sharing octahedra tilt angles range from 14–49°. There are a spread of Ba–O bond distances ranging from 2.86–3.14 Å. There are five inequivalent Ti+3.08+ sites. In the first Ti+3.08+ site, Ti+3.08+ is bonded to six O2- atoms to form TiO6 octahedra that share corners with three equivalent BaO12 cuboctahedra, corners with four TiO6 octahedra, an edgeedge with one BaO12 cuboctahedra, and edges with six TiO6 octahedra. The corner-sharing octahedra tilt angles range from 46–56°. There are a spread of Ti–O bond distances ranging from 2.01–2.10 Å. In the second Ti+3.08+ site, Ti+3.08+ is bonded to six O2- atoms to form TiO6 octahedra that share corners with two equivalent BaO12 cuboctahedra, corners with four TiO6 octahedra, edges with five TiO6 octahedra, and faces with two equivalent BaO12 cuboctahedra.
