... offer a fascinating example for the transi- tion from the infinite crystal lattice to the molecular state. In this case, not 6, 10, or 14, but 60 carbon atoms are used as cutouts of the ... atoms”. [l] This definition, originally proposed by Cotton in 1966, is valuable from a conceptual point of view, although it is difficult to apply since there is generally no simple way to ... coordination at any atom. [94] On the other hand, clusters containing from a few hundred to a few thousand atoms exhibit transi- tions from icosahedral to decahedral and finally to face-centered...
