Figure 14. (A) A crystal model of Chevrel phase (CP) Mo6S8 viewed along the [211] direction, featuring three types of highly symmetric sites: 3a, 3b, and 9d. (B) Sublattice corresponding to sites 3a and 3b. (C) The inner and outer rings can hop between partially occupied external and internal sites. (A-C) Reprinted with permission from[170].
