Materials Data on Nb9PO25 by Materials Project
Abstract
Nb9PO25 crystallizes in the monoclinic C2 space group. The structure is three-dimensional. there are five inequivalent Nb5+ sites. In the first Nb5+ site, Nb5+ is bonded to six O2- atoms to form distorted NbO6 octahedra that share corners with four NbO6 octahedra, a cornercorner with one PO4 tetrahedra, and edges with two equivalent NbO6 octahedra. The corner-sharing octahedra tilt angles range from 3–32°. There are a spread of Nb–O bond distances ranging from 1.80–2.33 Å. In the second Nb5+ site, Nb5+ is bonded to six O2- atoms to form distorted NbO6 octahedra that share corners with four NbO6 octahedra, a cornercorner with one PO4 tetrahedra, and edges with two equivalent NbO6 octahedra. The corner-sharing octahedra tilt angles range from 3–32°. There are a spread of Nb–O bond distances ranging from 1.80–2.33 Å. In the third Nb5+ site, Nb5+ is bonded to six O2- atoms to form corner-sharing NbO6 octahedra. The corner-sharing octahedra tilt angles range from 0–9°. There are a spread of Nb–O bond distances ranging from 1.83–2.06 Å. In the fourth Nb5+ site, Nb5+ is bonded to six O2- atoms to form a mixture of distorted edge and corner-sharing NbO6 octahedra. The corner-sharing octahedra tilt angles range from 3–31°.more »
