Title: Materials Data on NbO2F by Materials Project

Abstract

NbO2F is High-temperature superconductor-derived structured and crystallizes in the triclinic P-1 space group. The structure is three-dimensional. there are three inequivalent Nb5+ sites. In the first Nb5+ site, Nb5+ is bonded to four O2- and two F1- atoms to form corner-sharing NbO4F2 octahedra. The corner-sharing octahedra tilt angles range from 0–7°. There are a spread of Nb–O bond distances ranging from 1.91–2.03 Å. There are one shorter (2.05 Å) and one longer (2.09 Å) Nb–F bond lengths. In the second Nb5+ site, Nb5+ is bonded to four O2- and two F1- atoms to form corner-sharing NbO4F2 octahedra. The corner-sharing octahedra tilt angles range from 4–15°. There are a spread of Nb–O bond distances ranging from 1.88–2.08 Å. There are one shorter (2.00 Å) and one longer (2.15 Å) Nb–F bond lengths. In the third Nb5+ site, Nb5+ is bonded to four O2- and two F1- atoms to form corner-sharing NbO4F2 octahedra. The corner-sharing octahedra tilt angles range from 0–15°. There are a spread of Nb–O bond distances ranging from 1.84–2.01 Å. There are one shorter (2.16 Å) and one longer (2.25 Å) Nb–F bond lengths. There are eight inequivalent O2- sites. In the first O2- site, O2- is bonded inmore » a linear geometry to two Nb5+ atoms. In the second O2- site, O2- is bonded in a linear geometry to two Nb5+ atoms. In the third O2- site, O2- is bonded in a linear geometry to two equivalent Nb5+ atoms. In the fourth O2- site, O2- is bonded in a linear geometry to two Nb5+ atoms. In the fifth O2- site, O2- is bonded in a distorted linear geometry to two Nb5+ atoms. In the sixth O2- site, O2- is bonded in a linear geometry to two equivalent Nb5+ atoms. In the seventh O2- site, O2- is bonded in a linear geometry to two equivalent Nb5+ atoms. In the eighth O2- site, O2- is bonded in a linear geometry to two equivalent Nb5+ atoms. There are four inequivalent F1- sites. In the first F1- site, F1- is bonded in a linear geometry to two equivalent Nb5+ atoms. In the second F1- site, F1- is bonded in a linear geometry to two Nb5+ atoms. In the third F1- site, F1- is bonded in a distorted linear geometry to two Nb5+ atoms. In the fourth F1- site, F1- is bonded in a linear geometry to two equivalent Nb5+ atoms.« less
