Materials Data on LuTl(WO4)2 by Materials Project
LuTl(WO4)2 crystallizes in the monoclinic C2/c space group. The structure is three-dimensional. Lu3+ is bonded in a 6-coordinate geometry to six O2- atoms. There are a spread of Lu–O bond distances ranging from 2.22–2.27 Å. W6+ is bonded to six O2- atoms to form a mixture of corner and edge-sharing WO6 octahedra. The corner-sharing octahedral tilt angles are 44°. There are a spread of W–O bond distances ranging from 1.84–2.14 Å. Tl1+ is bonded in a 12-coordinate geometry to ten O2- atoms. There are a spread of Tl–O bond distances ranging from 2.84–3.11 Å. There are four inequivalent O2- sites. In the first O2- site, O2- is bonded in a 4-coordinate geometry to two equivalent W6+ and two equivalent Tl1+ atoms. In the second O2- site, O2- is bonded in a 2-coordinate geometry to one Lu3+, one W6+, and one Tl1+ atom. In the third O2- site, O2- is bonded in a 3-coordinate geometry to one Lu3+, two equivalent W6+, and one Tl1+ atom. In the fourth O2- site, O2- is bonded in a distorted bent 150 degrees geometry to one Lu3+, one W6+, and one Tl1+ atom.
