Materials Data on Fe(Mo3S4)2 by Materials Project
Fe(Mo3S4)2 crystallizes in the trigonal R-3 space group. The structure is three-dimensional. Mo+2.17+ 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 2.43–2.54 Å. Fe3+ is bonded in a distorted linear geometry to two equivalent S2- atoms. Both Fe–S bond lengths are 2.32 Å. There are two inequivalent S2- sites. In the first S2- site, S2- is bonded in a 1-coordinate geometry to three equivalent Mo+2.17+ and one Fe3+ atom. In the second S2- site, S2- is bonded in a 5-coordinate geometry to four equivalent Mo+2.17+ atoms.
