Materials Data on Ti5PO11 by Materials Project
Ti5PO11 crystallizes in the monoclinic P2_1/c space group. The structure is three-dimensional. there are five inequivalent Ti+3.40+ sites. In the first Ti+3.40+ site, Ti+3.40+ 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 45–52°. There are a spread of Ti–O bond distances ranging from 1.93–2.12 Å. In the second Ti+3.40+ site, Ti+3.40+ 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 17–52°. There are a spread of Ti–O bond distances ranging from 1.91–2.12 Å. In the third Ti+3.40+ site, Ti+3.40+ 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 45–51°. There are a spread of Ti–O bond distances ranging from 1.94–2.19 Å. In the fourth Ti+3.40+ site, Ti+3.40+ is bonded to six O2- atoms to form a mixture of edge and corner-sharing TiO6 octahedra.
