Materials Data on LiEuTiO4 by Materials Project

Abstract

LiEuTiO4 crystallizes in the orthorhombic Pbcm space group. The structure is three-dimensional. Li1+ is bonded in a 4-coordinate geometry to four equivalent O2- atoms. There are two shorter (2.02 Å) and two longer (2.03 Å) Li–O bond lengths. Eu3+ is bonded in a 8-coordinate geometry to eight O2- atoms. There are a spread of Eu–O bond distances ranging from 2.28–2.71 Å. Ti4+ is bonded in a 5-coordinate geometry to five O2- atoms. There are a spread of Ti–O bond distances ranging from 1.79–1.95 Å. There are four inequivalent O2- sites. In the first O2- site, O2- is bonded in a 2-coordinate geometry to two equivalent Eu3+ and two equivalent Ti4+ atoms. In the second O2- site, O2- is bonded in a 4-coordinate geometry to two equivalent Eu3+ and two equivalent Ti4+ atoms. In the third O2- site, O2- is bonded in a 2-coordinate geometry to four equivalent Eu3+ atoms. In the fourth O2- site, O2- is bonded in a 5-coordinate geometry to four equivalent Li1+ and one Ti4+ atom.
