Title: Materials Data on Ba2La3Ti3NbO15 by Materials Project

Abstract

Ba2La3Ti3NbO15 crystallizes in the trigonal P3c1 space group. The structure is three-dimensional. there are two inequivalent Ba2+ sites. In the first Ba2+ site, Ba2+ is bonded in a 12-coordinate geometry to twelve O2- atoms. There are a spread of Ba–O bond distances ranging from 2.73–3.28 Å. In the second Ba2+ site, Ba2+ is bonded in a 12-coordinate geometry to twelve O2- atoms. There are a spread of Ba–O bond distances ranging from 2.73–3.37 Å. There are three inequivalent La3+ sites. In the first La3+ site, La3+ is bonded in a 6-coordinate geometry to six O2- atoms. There are three shorter (2.43 Å) and three longer (2.58 Å) La–O bond lengths. In the second La3+ site, La3+ is bonded in a 9-coordinate geometry to nine O2- atoms. There are a spread of La–O bond distances ranging from 2.52–2.91 Å. In the third La3+ site, La3+ is bonded in a 9-coordinate geometry to nine O2- atoms. There are a spread of La–O bond distances ranging from 2.50–2.74 Å. There are three inequivalent Ti4+ sites. In the first Ti4+ site, Ti4+ is bonded to six O2- atoms to form corner-sharing TiO6 octahedra. The corner-sharing octahedra tilt angles range from 19–21°. There is threemore » shorter (1.91 Å) and three longer (2.08 Å) Ti–O bond length. In the second Ti4+ site, Ti4+ is bonded to six O2- atoms to form TiO6 octahedra that share corners with three equivalent TiO6 octahedra and corners with three equivalent NbO6 octahedra. The corner-sharing octahedra tilt angles range from 19–20°. There is three shorter (1.98 Å) and three longer (1.99 Å) Ti–O bond length. In the third Ti4+ site, Ti4+ is bonded to six O2- atoms to form distorted corner-sharing TiO6 octahedra. The corner-sharing octahedral tilt angles are 21°. There are three shorter (1.83 Å) and three longer (2.21 Å) Ti–O bond lengths. Nb5+ is bonded to six O2- atoms to form distorted NbO6 octahedra that share corners with three equivalent TiO6 octahedra. The corner-sharing octahedral tilt angles are 20°. There are three shorter (1.89 Å) and three longer (2.18 Å) Nb–O bond lengths. There are five inequivalent O2- sites. In the first O2- site, O2- is bonded in a 1-coordinate geometry to three Ba2+, one La3+, and one Ti4+ atom. In the second O2- site, O2- is bonded in a 3-coordinate geometry to two La3+ and two Ti4+ atoms. In the third O2- site, O2- is bonded in a 4-coordinate geometry to one Ba2+, two La3+, and two Ti4+ atoms. In the fourth O2- site, O2- is bonded in a 4-coordinate geometry to one Ba2+, two La3+, one Ti4+, and one Nb5+ atom. In the fifth O2- site, O2- is bonded in a distorted single-bond geometry to three Ba2+, one La3+, and one Nb5+ atom.« less
