Materials Data on Sc2TeO6 by Materials Project
Sc2TeO6 is Hydrophilite-derived structured and crystallizes in the trigonal P321 space group. The structure is three-dimensional. there are two inequivalent Sc3+ sites. In the first Sc3+ site, Sc3+ is bonded to six O2- atoms to form ScO6 octahedra that share corners with two equivalent TeO6 octahedra, corners with six equivalent ScO6 octahedra, and edges with two equivalent TeO6 octahedra. The corner-sharing octahedra tilt angles range from 52–55°. There are a spread of Sc–O bond distances ranging from 2.08–2.21 Å. In the second Sc3+ site, Sc3+ is bonded to six O2- atoms to form ScO6 octahedra that share corners with four equivalent TeO6 octahedra, corners with six equivalent ScO6 octahedra, and an edgeedge with one TeO6 octahedra. The corner-sharing octahedra tilt angles range from 48–53°. There are a spread of Sc–O bond distances ranging from 2.09–2.22 Å. There are two inequivalent Te6+ sites. In the first Te6+ site, Te6+ is bonded to six equivalent O2- atoms to form TeO6 octahedra that share corners with six equivalent ScO6 octahedra and edges with three equivalent ScO6 octahedra. The corner-sharing octahedral tilt angles are 55°. All Te–O bond lengths are 1.94 Å. In the second Te6+ site, Te6+ is bonded to six O2- atoms to form TeO6 octahedra that share corners with six equivalent ScO6 octahedra and edges with three equivalent ScO6 octahedra. The corner-sharing octahedra tilt angles range from 48–53°. All Te–O bond lengths are 1.95 Å. There are three inequivalent O2- sites. In the first O2- site, O2- is bonded in a trigonal planar geometry to two Sc3+ and one Te6+ atom. In the second O2- site, O2- is bonded in a distorted trigonal planar geometry to two Sc3+ and one Te6+ atom. In the third O2- site, O2- is bonded in a distorted trigonal planar geometry to two Sc3+ and one Te6+ atom.
