Title: Materials Data on YbTi2O5F by Materials Project

Abstract

YbTi2O5F crystallizes in the orthorhombic P2_12_12 space group. The structure is three-dimensional. there are two inequivalent Yb3+ sites. In the first Yb3+ site, Yb3+ is bonded in a 8-coordinate geometry to six O2- and two equivalent F1- atoms. There are a spread of Yb–O bond distances ranging from 2.34–2.53 Å. Both Yb–F bond lengths are 2.37 Å. In the second Yb3+ site, Yb3+ is bonded in a 8-coordinate geometry to six O2- and two equivalent F1- atoms. There are a spread of Yb–O bond distances ranging from 2.33–2.52 Å. Both Yb–F bond lengths are 2.30 Å. There are two inequivalent Ti4+ sites. In the first Ti4+ site, Ti4+ is bonded to six O2- atoms to form a mixture of distorted corner and edge-sharing TiO6 octahedra. The corner-sharing octahedra tilt angles range from 48–51°. There are a spread of Ti–O bond distances ranging from 1.79–2.21 Å. In the second Ti4+ site, Ti4+ is bonded to five O2- and one F1- atom to form TiO5F octahedra that share corners with four TiO5F octahedra and edges with two equivalent TiO6 octahedra. The corner-sharing octahedra tilt angles range from 48–51°. There are a spread of Ti–O bond distances ranging from 1.87–2.08 Å. The Ti–Fmore » bond length is 2.00 Å. There are five inequivalent O2- sites. In the first O2- site, O2- is bonded in a 4-coordinate geometry to two Yb3+ and two Ti4+ atoms. In the second O2- site, O2- is bonded in a 4-coordinate geometry to two Yb3+ and two Ti4+ atoms. In the third O2- site, O2- is bonded in a distorted trigonal planar geometry to three Ti4+ atoms. In the fourth O2- site, O2- is bonded in a 3-coordinate geometry to three Ti4+ atoms. In the fifth O2- site, O2- is bonded in a 1-coordinate geometry to two Yb3+ and one Ti4+ atom. F1- is bonded in a 3-coordinate geometry to two Yb3+ and one Ti4+ atom.« less
