Title: Materials Data on Ti4O7 by Materials Project

Abstract

Ti4O7 crystallizes in the triclinic P-1 space group. The structure is three-dimensional. there are eight inequivalent Ti+3.50+ sites. In the first Ti+3.50+ site, Ti+3.50+ is bonded to six O2- atoms to form TiO6 octahedra that share corners with three equivalent TiO6 octahedra, corners with three equivalent TiO5 trigonal bipyramids, and edges with two TiO6 octahedra. The corner-sharing octahedra tilt angles range from 46–56°. There are a spread of Ti–O bond distances ranging from 1.97–2.10 Å. In the second Ti+3.50+ site, Ti+3.50+ is bonded in a 5-coordinate geometry to five O2- atoms. There are a spread of Ti–O bond distances ranging from 1.85–2.19 Å. In the third Ti+3.50+ site, Ti+3.50+ is bonded to five O2- atoms to form distorted TiO5 trigonal bipyramids that share corners with three TiO6 octahedra, an edgeedge with one TiO6 octahedra, and an edgeedge with one TiO5 trigonal bipyramid.
