Materials Data on Sm(Mo3S4)2 by Materials Project

SmMo6S8 crystallizes in the trigonal R-3 space group. The structure is three-dimensional. Sm3+ is bonded in a body-centered cubic geometry to eight S2- atoms. There are two shorter (2.77 Å) and six longer (3.01 Å) Sm–S bond lengths. Mo+2.17+ 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 2.41–2.59 Å. There are two inequivalent S2- sites. In the first S2- site, S2- is bonded in a 5-coordinate geometry to one Sm3+ and four equivalent Mo+2.17+ atoms. In the second S2- site, S2- is bonded in a 4-coordinate geometry to one Sm3+ and three equivalent Mo+2.17+ atoms.
