The structure described by SnMo6S8 crystallizes in the trigonal R-3 space group. Mo(1) is bonded to one S(1) and four equivalent S(2) atoms to form a mixture of distorted edge and corner-sharing MoS5 square pyramids. Sn(1) is bonded in a distorted body-centered cubic geometry to two equivalent S(1) and six equivalent S(2) atoms. There are two inequivalent S sites. In the first S site, S(1) is bonded in a 4-coordinate geometry to three equivalent Mo(1) and one Sn(1) atom. In the second S site, S(2) is bonded in a 5-coordinate geometry to four equivalent Mo(1) and one Sn(1) atom. is represented by the CIF file [CIF]
