Materials Data on Ba2SrTeO6 by Materials Project
Ba2SrTeO6 is Orthorhombic Perovskite-derived structured and crystallizes in the trigonal R-3 space group. The structure is three-dimensional. Ba2+ is bonded in a 9-coordinate geometry to nine equivalent O2- atoms. There are a spread of Ba–O bond distances ranging from 2.79–3.14 Å. Sr2+ is bonded to six equivalent O2- atoms to form SrO6 octahedra that share corners with six equivalent TeO6 octahedra. The corner-sharing octahedral tilt angles are 17°. All Sr–O bond lengths are 2.44 Å. Te6+ is bonded to six equivalent O2- atoms to form TeO6 octahedra that share corners with six equivalent SrO6 octahedra. The corner-sharing octahedral tilt angles are 17°. All Te–O bond lengths are 1.96 Å. O2- is bonded in a 5-coordinate geometry to three equivalent Ba2+, one Sr2+, and one Te6+ atom.
