Materials Data on SrTeO3 by Materials Project

Abstract

SrTeO3 crystallizes in the monoclinic P2_1/c space group. The structure is three-dimensional. Sr2+ is bonded in a 7-coordinate geometry to seven O2- atoms. There are a spread of Sr–O bond distances ranging from 2.54–2.84 Å. Te4+ is bonded in a distorted trigonal non-coplanar geometry to three O2- atoms. There are a spread of Te–O bond distances ranging from 1.88–1.90 Å. There are three inequivalent O2- sites. In the first O2- site, O2- is bonded in a 4-coordinate geometry to three equivalent Sr2+ and one Te4+ atom. In the second O2- site, O2- is bonded in a 3-coordinate geometry to two equivalent Sr2+ and one Te4+ atom. In the third O2- site, O2- is bonded in a 3-coordinate geometry to two equivalent Sr2+ and one Te4+ atom.
