Materials Data on B2TeO6 by Materials Project
B2TeO6 crystallizes in the monoclinic P2_1/c space group. The structure is three-dimensional. there are two inequivalent B3+ sites. In the first B3+ site, B3+ is bonded in a trigonal planar geometry to three O2- atoms. There is one shorter (1.37 Å) and two longer (1.40 Å) B–O bond length. In the second B3+ site, B3+ is bonded in a trigonal planar geometry to three O2- atoms. All B–O bond lengths are 1.38 Å. Te6+ is bonded in an octahedral geometry to six O2- atoms. There are a spread of Te–O bond distances ranging from 1.93–1.99 Å. There are six inequivalent O2- sites. In the first O2- site, O2- is bonded in a 2-coordinate geometry to one B3+ and one Te6+ atom. In the second O2- site, O2- is bonded in a distorted bent 120 degrees geometry to one B3+ and one Te6+ atom. In the third O2- site, O2- is bonded in an L-shaped geometry to one B3+ and one Te6+ atom. In the fourth O2- site, O2- is bonded in a distorted bent 120 degrees geometry to one B3+ and one Te6+ atom. In the fifth O2- site, O2- is bonded in a distorted bent 120 degrees geometry to one B3+ and one Te6+ atom. In the sixth O2- site, O2- is bonded in an L-shaped geometry to one B3+ and one Te6+ atom.
