Title: Materials Data on Lu10Ti6O27 by Materials Project

Abstract

Lu10Ti6O27 crystallizes in the monoclinic Cm space group. The structure is three-dimensional. there are eight inequivalent Lu3+ sites. In the first Lu3+ site, Lu3+ is bonded to seven O2- atoms to form distorted LuO7 pentagonal bipyramids that share a cornercorner with one TiO6 octahedra and edges with two equivalent TiO6 octahedra. The corner-sharing octahedral tilt angles are 71°. There are a spread of Lu–O bond distances ranging from 2.12–2.43 Å. In the second Lu3+ site, Lu3+ is bonded in a 6-coordinate geometry to six O2- atoms. There are a spread of Lu–O bond distances ranging from 2.19–2.29 Å. In the third Lu3+ site, Lu3+ is bonded in a 6-coordinate geometry to six O2- atoms. There are a spread of Lu–O bond distances ranging from 2.11–2.32 Å.
