Title: Materials Data on Ba2TbNbO6 by Materials Project

Abstract

Ba2TbNbO6 crystallizes in the tetragonal I4/m space group. The structure is three-dimensional. Ba2+ is bonded to twelve O2- atoms to form distorted BaO12 cuboctahedra that share corners with twelve equivalent BaO12 cuboctahedra, faces with six equivalent BaO12 cuboctahedra, faces with four equivalent TbO6 octahedra, and faces with four equivalent NbO6 octahedra. There are a spread of Ba–O bond distances ranging from 2.85–3.24 Å. Tb3+ is bonded to six O2- atoms to form TbO6 octahedra that share corners with six equivalent NbO6 octahedra and faces with eight equivalent BaO12 cuboctahedra. The corner-sharing octahedra tilt angles range from 0–15°. There are two shorter (2.27 Å) and four longer (2.28 Å) Tb–O bond lengths. Nb5+ is bonded to six O2- atoms to form NbO6 octahedra that share corners with six equivalent TbO6 octahedra and faces with eight equivalent BaO12 cuboctahedra. The corner-sharing octahedra tilt angles range from 0–15°. All Nb–O bond lengths are 2.03 Å. There are two inequivalent O2- sites. In the first O2- site, O2- is bonded in a 2-coordinate geometry to four equivalent Ba2+, one Tb3+, and one Nb5+ atom. In the second O2- site, O2- is bonded in a distorted linear geometry to four equivalent Ba2+, one Tb3+, andmore » one Nb5+ atom.« less
