Title: Materials Data on Nb3O7F by Materials Project

Abstract

Nb3O7F crystallizes in the orthorhombic Cmmm space group. The structure is three-dimensional. there are two inequivalent Nb5+ sites. In the first Nb5+ site, Nb5+ is bonded to six O2- atoms to form a mixture of edge and corner-sharing NbO6 octahedra. The corner-sharing octahedra tilt angles range from 0–30°. There are a spread of Nb–O bond distances ranging from 1.93–2.24 Å. In the second Nb5+ site, Nb5+ is bonded to four O2- and two equivalent F1- atoms to form corner-sharing NbO4F2 octahedra. The corner-sharing octahedral tilt angles are 0°. There is two shorter (1.95 Å) and two longer (1.96 Å) Nb–O bond length. Both Nb–F bond lengths are 1.99 Å. There are four inequivalent O2- sites. In the first O2- site, O2- is bonded in a linear geometry to two Nb5+ atoms. In the second O2- site, O2- is bonded in a linear geometry to two equivalent Nb5+ atoms. In the third O2- site, O2- is bonded in a 3-coordinate geometry to three equivalent Nb5+ atoms. In the fourth O2- site, O2- is bonded in a linear geometry to two equivalent Nb5+ atoms. F1- is bonded in a linear geometry to two equivalent Nb5+ atoms.
