Materials Data on FeMo3S4 by Materials Project
Mo3FeS4 crystallizes in the triclinic P-1 space group. The structure is three-dimensional. there are three inequivalent Mo2+ sites. In the first Mo2+ site, Mo2+ is bonded to five S2- atoms to form a mixture of edge and corner-sharing MoS5 square pyramids. There are a spread of Mo–S bond distances ranging from 2.45–2.52 Å. In the second Mo2+ site, Mo2+ is bonded to five S2- atoms to form a mixture of edge and corner-sharing MoS5 square pyramids. There are a spread of Mo–S bond distances ranging from 2.40–2.57 Å. In the third Mo2+ site, Mo2+ is bonded to five S2- atoms to form a mixture of edge and corner-sharing MoS5 square pyramids. There are a spread of Mo–S bond distances ranging from 2.42–2.62 Å. Fe2+ is bonded in a 5-coordinate geometry to five S2- atoms. There are a spread of Fe–S bond distances ranging from 2.37–2.63 Å. There are four inequivalent S2- sites. In the first S2- site, S2- is bonded in a 5-coordinate geometry to four Mo2+ and one Fe2+ atom. In the second S2- site, S2- is bonded in a 5-coordinate geometry to three Mo2+ and two equivalent Fe2+ atoms. In the third S2- site, S2- is bonded in a 5-coordinate geometry to four Mo2+ and one Fe2+ atom. In the fourth S2- site, S2- is bonded in a 5-coordinate geometry to four Mo2+ and one Fe2+ atom.
