Title: Materials Data on Ti(FeSe2)2 by Materials Project

Abstract

Ti(FeSe2)2 crystallizes in the triclinic P1 space group. The structure is three-dimensional. Ti4+ is bonded to five Se2- atoms to form corner-sharing TiSe5 square pyramids. There are a spread of Ti–Se bond distances ranging from 2.51–2.65 Å. There are two inequivalent Fe2+ sites. In the first Fe2+ site, Fe2+ is bonded in a 5-coordinate geometry to one Fe2+ and five Se2- atoms. The Fe–Fe bond length is 2.42 Å. There are a spread of Fe–Se bond distances ranging from 2.33–2.59 Å. In the second Fe2+ site, Fe2+ is bonded in a 6-coordinate geometry to one Fe2+ and five Se2- atoms. There are a spread of Fe–Se bond distances ranging from 2.44–2.69 Å. There are four inequivalent Se2- sites. In the first Se2- site, Se2- is bonded in a 5-coordinate geometry to two equivalent Ti4+ and three Fe2+ atoms. In the second Se2- site, Se2- is bonded in a 4-coordinate geometry to one Ti4+ and two Fe2+ atoms. In the third Se2- site, Se2- is bonded in a 4-coordinate geometry to one Ti4+ and two Fe2+ atoms. In the fourth Se2- site, Se2- is bonded in a 4-coordinate geometry to one Ti4+ and three Fe2+ atoms.
