Title: Materials Data on Nb2PbO6 by Materials Project

Abstract

In the first Nb5+ site, Nb5+ is bonded to six O2- atoms to form distorted corner-sharing NbO6 octahedra. The corner-sharing octahedra tilt angles range from 7–36°. There are a spread of Nb–O bond distances ranging from 1.83–2.37 Å. In the second Nb5+ site, Nb5+ is bonded to six O2- atoms to form distorted corner-sharing NbO6 octahedra. The corner-sharing octahedra tilt angles range from 8–46°. There are a spread of Nb–O bond distances ranging from 1.84–2.39 Å.
