Materials Data on BaTeO4 by Materials Project
BaTeO4 crystallizes in the orthorhombic Pbcn space group. The structure is three-dimensional. Ba2+ is bonded to six O2- atoms to form distorted BaO6 octahedra that share corners with four equivalent BaO6 octahedra, corners with six equivalent TeO6 octahedra, and an edgeedge with one TeO6 octahedra. The corner-sharing octahedra tilt angles range from 48–65°. There are a spread of Ba–O bond distances ranging from 2.69–2.78 Å. Te6+ is bonded to six O2- atoms to form TeO6 octahedra that share corners with six equivalent BaO6 octahedra, an edgeedge with one BaO6 octahedra, and edges with two equivalent TeO6 octahedra. The corner-sharing octahedra tilt angles range from 48–58°. There are a spread of Te–O bond distances ranging from 1.88–2.04 Å. There are two inequivalent O2- sites. In the first O2- site, O2- is bonded in a 3-coordinate geometry to two equivalent Ba2+ and one Te6+ atom. In the second O2- site, O2- is bonded in a distorted trigonal planar geometry to one Ba2+ and two equivalent Te6+ atoms.
