Title: Materials Data on Tm2TeO6 by Materials Project

Abstract

Tm2TeO6 is Hydrophilite-derived structured and crystallizes in the trigonal P321 space group. The structure is three-dimensional. there are two inequivalent Tm3+ sites. In the first Tm3+ site, Tm3+ is bonded to six O2- atoms to form TmO6 octahedra that share corners with four equivalent TeO6 octahedra, corners with six equivalent TmO6 octahedra, and an edgeedge with one TeO6 octahedra. The corner-sharing octahedra tilt angles range from 47–56°. There are a spread of Tm–O bond distances ranging from 2.21–2.33 Å. In the second Tm3+ site, Tm3+ is bonded to six O2- atoms to form distorted TmO6 octahedra that share corners with two equivalent TeO6 octahedra, corners with six equivalent TmO6 octahedra, and edges with two equivalent TeO6 octahedra. The corner-sharing octahedra tilt angles range from 54–56°. There are a spread of Tm–O bond distances ranging from 2.19–2.31 Å. There are two inequivalent Te6+ sites. In the first Te6+ site, Te6+ is bonded to six O2- atoms to form TeO6 octahedra that share corners with six equivalent TmO6 octahedra and edges with three equivalent TmO6 octahedra. The corner-sharing octahedra tilt angles range from 47–50°. There is three shorter (1.95 Å) and three longer (1.96 Å) Te–O bond length. In the second Te6+more » site, Te6+ is bonded to six equivalent O2- atoms to form TeO6 octahedra that share corners with six equivalent TmO6 octahedra and edges with three equivalent TmO6 octahedra. The corner-sharing octahedral tilt angles are 55°. All Te–O bond lengths are 1.94 Å. There are three inequivalent O2- sites. In the first O2- site, O2- is bonded in a trigonal planar geometry to two Tm3+ and one Te6+ atom. In the second O2- site, O2- is bonded in a distorted trigonal planar geometry to two Tm3+ and one Te6+ atom. In the third O2- site, O2- is bonded in a distorted trigonal planar geometry to two Tm3+ and one Te6+ atom.« less
