Materials Data on LiEr(WO4)2 by Materials Project
LiEr(WO4)2 crystallizes in the monoclinic P2/c space group. The structure is three-dimensional. Li1+ is bonded in a 4-coordinate geometry to four O2- atoms. There are two shorter (2.05 Å) and two longer (2.15 Å) Li–O bond lengths. Er3+ is bonded to six O2- atoms to form distorted ErO6 octahedra that share corners with eight equivalent WO6 octahedra. The corner-sharing octahedra tilt angles range from 47–61°. There are a spread of Er–O bond distances ranging from 2.22–2.34 Å. W6+ is bonded to six O2- atoms to form distorted WO6 octahedra that share corners with four equivalent ErO6 octahedra and edges with two equivalent WO6 octahedra. The corner-sharing octahedra tilt angles range from 47–61°. There are a spread of W–O bond distances ranging from 1.82–2.23 Å. There are four inequivalent O2- sites. In the first O2- site, O2- is bonded in a distorted bent 120 degrees geometry to one Er3+ and one W6+ atom. In the second O2- site, O2- is bonded in a distorted trigonal planar geometry to one Li1+, one Er3+, and one W6+ atom. In the third O2- site, O2- is bonded in a 3-coordinate geometry to one Li1+ and two equivalent W6+ atoms. In the fourth O2- site, O2- is bonded in a distorted trigonal planar geometry to one Er3+ and two equivalent W6+ atoms.
