Materials Data on Tl(WO3)6 by Materials Project
Tl(WO3)6 crystallizes in the trigonal P-31m space group. The structure is three-dimensional. W+5.83+ is bonded to six O2- atoms to form WO6 octahedra that share corners with six equivalent WO6 octahedra and edges with two equivalent TlO12 cuboctahedra. The corner-sharing octahedra tilt angles range from 0–29°. There is four shorter (1.93 Å) and two longer (1.96 Å) W–O bond length. Tl1+ is bonded to twelve equivalent O2- atoms to form TlO12 cuboctahedra that share edges with twelve equivalent WO6 octahedra. All Tl–O bond lengths are 3.37 Å. There are three inequivalent O2- sites. In the first O2- site, O2- is bonded in a bent 150 degrees geometry to two equivalent W+5.83+ and one Tl1+ atom. In the second O2- site, O2- is bonded in a linear geometry to two equivalent W+5.83+ atoms. In the third O2- site, O2- is bonded in a linear geometry to two equivalent W+5.83+ atoms.
