Materials Data on LiYb(WO4)2 by Materials Project

LiYb(WO4)2 crystallizes in the monoclinic P2/c space group. The structure is three-dimensional. Li1+ is bonded in a 6-coordinate geometry to six O2- atoms. There are a spread of Li–O bond distances ranging from 2.09–2.71 Å. Yb3+ is bonded to six O2- atoms to form YbO6 octahedra that share corners with eight equivalent WO6 octahedra. The corner-sharing octahedra tilt angles range from 48–55°. There are a spread of Yb–O bond distances ranging from 2.29–2.35 Å. W6+ is bonded to six O2- atoms to form distorted WO6 octahedra that share corners with four equivalent YbO6 octahedra and edges with two equivalent WO6 octahedra. The corner-sharing octahedra tilt angles range from 48–55°. There are a spread of W–O bond distances ranging from 1.81–2.20 Å. There are four inequivalent O2- sites. In the first O2- site, O2- is bonded in a 2-coordinate geometry to one Li1+, one Yb3+, and one W6+ atom. In the second O2- site, O2- is bonded in a distorted trigonal planar geometry to one Li1+, one Yb3+, and one W6+ atom. In the third O2- site, O2- is bonded in a distorted trigonal planar geometry to one Li1+ and two equivalent W6+ atoms. In the fourth O2- site, O2- is bonded in a trigonal planar geometry to one Yb3+ and two equivalent W6+ atoms.
