Materials Data on BaTeMo2O9 by Materials Project
BaTeMo2O9 crystallizes in the monoclinic P2_1 space group. The structure is three-dimensional. Ba2+ is bonded in a 11-coordinate geometry to eleven O2- atoms. There are a spread of Ba–O bond distances ranging from 2.74–3.39 Å. There are two inequivalent Mo6+ sites. In the first Mo6+ site, Mo6+ is bonded to six O2- atoms to form distorted corner-sharing MoO6 octahedra. The corner-sharing octahedra tilt angles range from 35–48°. There are a spread of Mo–O bond distances ranging from 1.76–2.20 Å. In the second Mo6+ site, Mo6+ is bonded to six O2- atoms to form distorted corner-sharing MoO6 octahedra. The corner-sharing octahedra tilt angles range from 35–48°. There are a spread of Mo–O bond distances ranging from 1.77–2.28 Å. Te4+ is bonded in a distorted rectangular see-saw-like geometry to four O2- atoms. There are a spread of Te–O bond distances ranging from 1.90–2.25 Å. There are nine inequivalent O2- sites. In the first O2- site, O2- is bonded in a distorted single-bond geometry to two equivalent Ba2+ and one Mo6+ atom. In the second O2- site, O2- is bonded in a distorted single-bond geometry to one Ba2+ and one Mo6+ atom. In the third O2- site, O2- is bonded in a distorted bent 120 degrees geometry to two Mo6+ atoms. In the fourth O2- site, O2- is bonded in a distorted single-bond geometry to three equivalent Ba2+ and one Mo6+ atom. In the fifth O2- site, O2- is bonded in a 3-coordinate geometry to two Mo6+ and one Te4+ atom. In the sixth O2- site, O2- is bonded in a 3-coordinate geometry to one Ba2+, one Mo6+, and one Te4+ atom. In the seventh O2- site, O2- is bonded in a distorted trigonal planar geometry to two Mo6+ and one Te4+ atom. In the eighth O2- site, O2- is bonded in a 1-coordinate geometry to two equivalent Ba2+, one Mo6+, and one Te4+ atom. In the ninth O2- site, O2- is bonded in a distorted single-bond geometry to two equivalent Ba2+ and one Mo6+ atom.
