Materials Data on Fe(Mo3Se4)2 by Materials Project

Abstract

Fe(Mo3Se4)2 crystallizes in the triclinic P-1 space group. The structure is three-dimensional. there are six inequivalent Mo+2.17+ sites. In the first Mo+2.17+ site, Mo+2.17+ is bonded to five Se2- atoms to form a mixture of corner and edge-sharing MoSe5 square pyramids. There are a spread of Mo–Se bond distances ranging from 2.56–2.75 Å. In the second Mo+2.17+ site, Mo+2.17+ is bonded to five Se2- atoms to form a mixture of corner and edge-sharing MoSe5 square pyramids. There are a spread of Mo–Se bond distances ranging from 2.56–2.66 Å. In the third Mo+2.17+ site, Mo+2.17+ is bonded to five Se2- atoms to form a mixture of corner and edge-sharing MoSe5 square pyramids. There are a spread of Mo–Se bond distances ranging from 2.56–2.73 Å. In the fourth Mo+2.17+ site, Mo+2.17+ is bonded to five Se2- atoms to form a mixture of corner and edge-sharing MoSe5 square pyramids. There are a spread of Mo–Se bond distances ranging from 2.59–2.71 Å. In the fifth Mo+2.17+ site, Mo+2.17+ is bonded to five Se2- atoms to form a mixture of corner and edge-sharing MoSe5 square pyramids. There are a spread of Mo–Se bond distances ranging from 2.58–2.74 Å. In the sixth Mo+2.17+ site, Mo+2.17+ is bonded to five Se2- atoms to form a mixture of corner and edge-sharing MoSe5 square pyramids. There are a spread of Mo–Se bond distances ranging from 2.55–2.74 Å. Fe3+ is bonded in a 4-coordinate geometry to four Se2- atoms. There are a spread of Fe–Se bond distances ranging from 2.41–2.57 Å. There are eight inequivalent Se2- sites. In the first Se2- site, Se2- is bonded in a 4-coordinate geometry to three Mo+2.17+ atoms. In the second Se2- site, Se2- is bonded in a 5-coordinate geometry to four Mo+2.17+ and one Fe3+ atom. In the third Se2- site, Se2- is bonded in a 4-coordinate geometry to four Mo+2.17+ atoms. In the fourth Se2- site, Se2- is bonded in a distorted rectangular see-saw-like geometry to four Mo+2.17+ atoms. In the fifth Se2- site, Se2- is bonded in a distorted rectangular see-saw-like geometry to four Mo+2.17+ atoms. In the sixth Se2- site, Se2- is bonded in a 1-coordinate geometry to four Mo+2.17+ and one Fe3+ atom. In the seventh Se2- site, Se2- is bonded in a 1-coordinate geometry to three Mo+2.17+ and one Fe3+ atom. In the eighth Se2- site, Se2- is bonded in a 5-coordinate geometry to four Mo+2.17+ and one Fe3+ atom.
