Title: Materials Data on Sr2Ti6O13 by Materials Project

Abstract

Sr2Ti6O13 crystallizes in the monoclinic C2/m space group. The structure is three-dimensional. Sr2+ is bonded in a 11-coordinate geometry to eleven O2- atoms. There are a spread of Sr–O bond distances ranging from 2.61–3.14 Å. There are three inequivalent Ti+3.67+ sites. In the first Ti+3.67+ site, Ti+3.67+ is bonded to six O2- atoms to form a mixture of edge and corner-sharing TiO6 octahedra. The corner-sharing octahedra tilt angles range from 0–17°. There are a spread of Ti–O bond distances ranging from 1.89–2.17 Å. In the second Ti+3.67+ site, Ti+3.67+ is bonded to six O2- atoms to form a mixture of distorted edge and corner-sharing TiO6 octahedra. The corner-sharing octahedral tilt angles are 30°. There are a spread of Ti–O bond distances ranging from 1.81–2.28 Å. In the third Ti+3.67+ site, Ti+3.67+ is bonded to six O2- atoms to form a mixture of edge and corner-sharing TiO6 octahedra. The corner-sharing octahedra tilt angles range from 15–17°. There are a spread of Ti–O bond distances ranging from 1.85–2.16 Å. There are seven inequivalent O2- sites. In the first O2- site, O2- is bonded in a linear geometry to four equivalent Sr2+ and two equivalent Ti+3.67+ atoms. In the second O2- site, O2-more » is bonded in a distorted rectangular see-saw-like geometry to one Sr2+ and four Ti+3.67+ atoms. In the third O2- site, O2- is bonded in a 4-coordinate geometry to two equivalent Sr2+ and two Ti+3.67+ atoms. In the fourth O2- site, O2- is bonded to four Ti+3.67+ atoms to form a mixture of distorted edge and corner-sharing OTi4 trigonal pyramids. In the fifth O2- site, O2- is bonded in a distorted water-like geometry to two equivalent Sr2+ and two Ti+3.67+ atoms. In the sixth O2- site, O2- is bonded in a distorted T-shaped geometry to two equivalent Sr2+ and three Ti+3.67+ atoms. In the seventh O2- site, O2- is bonded in a 2-coordinate geometry to two equivalent Sr2+ and two Ti+3.67+ atoms.« less
