Title: Materials Data on Li2EuSiO4 by Materials Project

Abstract

Li2EuSiO4 is Chalcostibite-derived structured and crystallizes in the trigonal P3_121 space group. The structure is three-dimensional. Li1+ is bonded to four O2- atoms to form LiO4 tetrahedra that share corners with four equivalent LiO4 tetrahedra and corners with four equivalent SiO4 tetrahedra. There are a spread of Li–O bond distances ranging from 1.96–2.04 Å. Eu2+ is bonded in a 8-coordinate geometry to eight O2- atoms. There are a spread of Eu–O bond distances ranging from 2.58–2.69 Å. Si4+ is bonded to four O2- atoms to form SiO4 tetrahedra that share corners with eight equivalent LiO4 tetrahedra. All Si–O bond lengths are 1.66 Å. There are two inequivalent O2- sites. In the first O2- site, O2- is bonded in a 3-coordinate geometry to two equivalent Li1+, two equivalent Eu2+, and one Si4+ atom. In the second O2- site, O2- is bonded in a distorted trigonal planar geometry to two equivalent Li1+, two equivalent Eu2+, and one Si4+ atom.
