Title: Materials Data on Tm10Ti6O27 by Materials Project

Abstract

In the second Tm3+ site, Tm3+ is bonded in a 7-coordinate geometry to seven O2- atoms. There are a spread of Tm–O bond distances ranging from 2.12–2.52 Å. In the third Tm3+ site, Tm3+ is bonded to six O2- atoms to form distorted corner-sharing TmO6 octahedra. There are a spread of Tm–O bond distances ranging from 2.16–2.37 Å.
