Materials Data on Sr3TeO6 by Materials Project

Sr3TeO6 is Ilmenite-like structured and crystallizes in the cubic Ia-3 space group. The structure is three-dimensional. Sr2+ is bonded in a 6-coordinate geometry to six O2- atoms. There are a spread of Sr–O bond distances ranging from 2.48–2.76 Å. There are two inequivalent Te6+ sites. In the first Te6+ site, Te6+ is bonded in an octahedral geometry to six equivalent O2- atoms. All Te–O bond lengths are 1.97 Å. In the second Te6+ site, Te6+ is bonded in an octahedral geometry to six equivalent O2- atoms. All Te–O bond lengths are 1.97 Å. There are two inequivalent O2- sites. In the first O2- site, O2- is bonded to three equivalent Sr2+ and one Te6+ atom to form a mixture of distorted edge and corner-sharing OSr3Te tetrahedra. In the second O2- site, O2- is bonded to three equivalent Sr2+ and one Te6+ atom to form a mixture of distorted edge and corner-sharing OSr3Te trigonal pyramids.
