Materials Data on Ti15NbO32 by Materials Project
Abstract
Ti15NbO32 is beta Vanadium nitride-derived structured and crystallizes in the tetragonal P-4m2 space group. The structure is three-dimensional. there are five inequivalent Ti4+ sites. In the first Ti4+ site, Ti4+ is bonded to six O2- atoms to form a mixture of distorted edge and corner-sharing TiO6 octahedra. The corner-sharing octahedra tilt angles range from 24–25°. There are a spread of Ti–O bond distances ranging from 1.94–2.01 Å. In the second Ti4+ site, Ti4+ is bonded to six O2- atoms to form distorted TiO6 octahedra that share corners with four TiO6 octahedra, an edgeedge with one NbO6 octahedra, and edges with three TiO6 octahedra. The corner-sharing octahedra tilt angles range from 23–28°. There are a spread of Ti–O bond distances ranging from 1.93–2.06 Å. In the third Ti4+ site, Ti4+ is bonded to six O2- atoms to form a mixture of distorted edge and corner-sharing TiO6 octahedra. The corner-sharing octahedra tilt angles range from 23–25°. There are a spread of Ti–O bond distances ranging from 1.95–2.01 Å. In the fourth Ti4+ site, Ti4+ is bonded to six O2- atoms to form distorted TiO6 octahedra that share corners with two equivalent TiO6 octahedra, corners with two equivalent NbO6 octahedra, and edges withmore »
