Materials Data on Ti9O10 by Materials Project
Ti9O10 crystallizes in the monoclinic C2/m space group. The structure is three-dimensional. there are four inequivalent Ti+2.22+ sites. In the first Ti+2.22+ site, Ti+2.22+ is bonded in a rectangular see-saw-like geometry to four equivalent O2- atoms. There are two shorter (2.00 Å) and two longer (2.11 Å) Ti–O bond lengths. In the second Ti+2.22+ site, Ti+2.22+ is bonded to five O2- atoms to form TiO5 square pyramids that share corners with three TiO6 octahedra, a cornercorner with one TiO5 square pyramid, edges with three TiO6 octahedra, and edges with two equivalent TiO5 square pyramids. The corner-sharing octahedra tilt angles range from 6–8°. There are a spread of Ti–O bond distances ranging from 1.96–2.14 Å. In the third Ti+2.22+ site, Ti+2.22+ is bonded to six O2- atoms to form TiO6 octahedra that share corners with four equivalent TiO5 square pyramids, edges with six TiO6 octahedra, and edges with four equivalent TiO5 square pyramids. There are a spread of Ti–O bond distances ranging from 2.06–2.15 Å. In the fourth Ti+2.22+ site, Ti+2.22+ is bonded to six O2- atoms to form TiO6 octahedra that share corners with four equivalent TiO5 square pyramids, edges with six equivalent TiO6 octahedra, and edges with four equivalent TiO5 square pyramids. There are four shorter (2.09 Å) and two longer (2.16 Å) Ti–O bond lengths. There are three inequivalent O2- sites. In the first O2- site, O2- is bonded in a rectangular see-saw-like geometry to four Ti+2.22+ atoms. In the second O2- site, O2- is bonded to five Ti+2.22+ atoms to form a mixture of edge and corner-sharing OTi5 square pyramids. In the third O2- site, O2- is bonded to five Ti+2.22+ atoms to form a mixture of edge and corner-sharing OTi5 square pyramids.
