Materials Data on Tl3VSe4 by Materials Project
VTl3Se4 crystallizes in the cubic I-43m space group. The structure is three-dimensional and consists of two VTl3Se4 frameworks. V5+ is bonded in a tetrahedral geometry to four equivalent Se2- atoms. All V–Se bond lengths are 2.30 Å. Tl1+ is bonded in a 12-coordinate geometry to four equivalent Se2- atoms. All Tl–Se bond lengths are 3.23 Å. Se2- is bonded in a distorted single-bond geometry to one V5+ and three equivalent Tl1+ atoms.
