The structure described by PrMo6S8 crystallizes in the trigonal R-3 space group. Pr(1) is bonded in a body-centered cubic geometry to two equivalent S(1) and six equivalent S(2) atoms. 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. There are two inequivalent S sites. In the first S site, S(1) is bonded in a 4-coordinate geometry to one Pr(1) and three equivalent Mo(1) atoms. In the second S site, S(2) is bonded to one Pr(1) and four equivalent Mo(1) atoms to form a mixture of distorted edge and corner-sharing SPrMo4 trigonal bipyramids. is represented by the Crystallographic Information File (CIF) [CIF]
