Materials Data on Tl2MoO4 by Materials Project
Tl2MoO4 crystallizes in the monoclinic C2 space group. The structure is three-dimensional. Mo6+ is bonded to four O2- atoms to form MoO4 tetrahedra that share corners with three equivalent TlO6 octahedra. The corner-sharing octahedra tilt angles range from 10–52°. There are a spread of Mo–O bond distances ranging from 1.79–1.81 Å. There are three inequivalent Tl1+ sites. In the first Tl1+ site, Tl1+ is bonded in a 4-coordinate geometry to four O2- atoms. There are a spread of Tl–O bond distances ranging from 2.54–2.97 Å. In the second Tl1+ site, Tl1+ is bonded in a 2-coordinate geometry to ten O2- atoms. There are a spread of Tl–O bond distances ranging from 2.71–3.44 Å. In the third Tl1+ site, Tl1+ is bonded to six O2- atoms to form distorted TlO6 octahedra that share corners with six equivalent MoO4 tetrahedra. There are a spread of Tl–O bond distances ranging from 2.79–3.08 Å. There are four inequivalent O2- sites. In the first O2- site, O2- is bonded in a 1-coordinate geometry to one Mo6+ and three Tl1+ atoms. In the second O2- site, O2- is bonded in a 1-coordinate geometry to one Mo6+ and three Tl1+ atoms. In the third O2- site, O2- is bonded in a 1-coordinate geometry to one Mo6+ and three Tl1+ atoms. In the fourth O2- site, O2- is bonded in a distorted bent 150 degrees geometry to one Mo6+ and three Tl1+ atoms.
