(a) The guest atom ADPs as a function of temperature along with the fitted Einstein models and corresponding Einstein temperatures. (b) Average distance from 6d to the in- and out-of-plane atoms of the large tetrakaidecahedral cage. Here the out-of-plane atoms are defined as the eight 24k and four 6c atoms that comprise the two hexagonal faces, and the in-plane atoms the four 24k and eight 16i atoms that `zigzag' around the equatorial plane of the cage (see Figs. 2 and 7). |
