Materials Data on Tl2Fe3Se4 by Materials Project
Fe3Tl2Se4 crystallizes in the triclinic P-1 space group. The structure is three-dimensional. there are three inequivalent Fe2+ sites. In the first Fe2+ site, Fe2+ is bonded to four Se2- atoms to form a mixture of corner and edge-sharing FeSe4 tetrahedra. There are a spread of Fe–Se bond distances ranging from 2.38–2.42 Å. In the second Fe2+ site, Fe2+ is bonded to four Se2- atoms to form a mixture of corner and edge-sharing FeSe4 tetrahedra. All Fe–Se bond lengths are 2.38 Å. In the third Fe2+ site, Fe2+ is bonded to four Se2- atoms to form a mixture of corner and edge-sharing FeSe4 tetrahedra. There are a spread of Fe–Se bond distances ranging from 2.38–2.43 Å. There are three inequivalent Tl1+ sites. In the first Tl1+ site, Tl1+ is bonded in a body-centered cubic geometry to eight Se2- atoms. There are a spread of Tl–Se bond distances ranging from 3.38–3.51 Å. In the second Tl1+ site, Tl1+ is bonded in a body-centered cubic geometry to eight Se2- atoms. There are a spread of Tl–Se bond distances ranging from 3.42–3.47 Å. In the third Tl1+ site, Tl1+ is bonded in a body-centered cubic geometry to eight Se2- atoms. There are a spread of Tl–Se bond distances ranging from 3.41–3.49 Å. There are four inequivalent Se2- sites. In the first Se2- site, Se2- is bonded in a 3-coordinate geometry to three Fe2+ and four Tl1+ atoms. In the second Se2- site, Se2- is bonded in a 3-coordinate geometry to three Fe2+ and four Tl1+ atoms. In the third Se2- site, Se2- is bonded in a 3-coordinate geometry to three Fe2+ and four Tl1+ atoms. In the fourth Se2- site, Se2- is bonded in a 3-coordinate geometry to three Fe2+ and four Tl1+ atoms.
