Materials Data on Sr(Mo3S4)2 by Materials Project

Sr(Mo3S4)2 crystallizes in the trigonal R-3 space group. The structure is three-dimensional. Sr2+ is bonded in a body-centered cubic geometry to eight S2- atoms. There are two shorter (2.86 Å) and six longer (3.17 Å) Sr–S bond lengths. Mo+2.33+ is bonded to five S2- atoms to form a mixture of corner and edge-sharing MoS5 square pyramids. There are a spread of Mo–S bond distances ranging from 2.40–2.60 Å. There are two inequivalent S2- sites. In the first S2- site, S2- is bonded in a 4-coordinate geometry to one Sr2+ and three equivalent Mo+2.33+ atoms. In the second S2- site, S2- is bonded in a 5-coordinate geometry to one Sr2+ and four equivalent Mo+2.33+ atoms.

Materials Data on Sr(Mo3S4)2 by Materials Project

Sr(Mo3S4)2 crystallizes in the triclinic P-1 space group. The structure is three-dimensional. Sr2+ is bonded in a body-centered cubic geometry to eight S2- atoms. There are a spread of Sr–S bond distances ranging from 2.88–3.21 Å. There are three inequivalent Mo+2.33+ sites. In the first Mo+2.33+ site, Mo+2.33+ 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 2.38–2.62 Å. In the second Mo+2.33+ site, Mo+2.33+ 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 2.44–2.64 Å. In the third Mo+2.33+ site, Mo+2.33+ 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 2.39–2.62 Å. There are four inequivalent S2- sites. In the first S2- site, S2- is bonded in a 5-coordinate geometry to one Sr2+ and four Mo+2.33+ atoms. In the second S2- site, S2- is bonded in a 5-coordinate geometry to one Sr2+ and four Mo+2.33+ atoms. In the third S2- site, S2- is bonded in a 4-coordinate geometry to one Sr2+ and three Mo+2.33+ atoms. In the fourth S2- site, S2- is bonded in a 5-coordinate geometry to one Sr2+ and four Mo+2.33+ atoms.
