Materials Data on SrGeTeO6 by Materials Project

Abstract

SrGeTeO6 is beta Vanadium nitride-derived structured and crystallizes in the trigonal P312 space group. The structure is three-dimensional. Sr2+ is bonded to six equivalent O2- atoms to form SrO6 octahedra that share corners with six equivalent GeO6 octahedra and corners with six equivalent TeO6 octahedra. The corner-sharing octahedra tilt angles range from 52–53°. All Sr–O bond lengths are 2.56 Å. Ge4+ is bonded to six equivalent O2- atoms to form GeO6 octahedra that share corners with six equivalent SrO6 octahedra and edges with three equivalent TeO6 octahedra. The corner-sharing octahedral tilt angles are 52°. All Ge–O bond lengths are 1.93 Å. Te6+ is bonded to six equivalent O2- atoms to form TeO6 octahedra that share corners with six equivalent SrO6 octahedra and edges with three equivalent GeO6 octahedra. The corner-sharing octahedral tilt angles are 53°. All Te–O bond lengths are 1.96 Å. O2- is bonded in a distorted trigonal planar geometry to one Sr2+, one Ge4+, and one Te6+ atom.
