Charge of clusters

The overall charge of the cluster, 0/-1 for oxidized and reduced Rieske clusters, respectively, compared to -2/-3 for 4-cysteine coordinated [2Fe-2S] clusters... 

Moreover, as a consequence of their transient character, a hierarchy of clusters in dynamic equilibrium that may differ in shape and size can be hypothesized [253], Mass, momentum, and charge transport within a cluster of reversed micelles is expected to be strongly enhanced as compared to that among isolated reversed micelles. It has been shown that the dynamics of a network of interacting reversed micelles is successfully described by a model developed by Cates [35,69,254],... 

Figure 12-5 illustrates the solvation of Na and Cl" ions as NaCl dissolves in water. A cluster of water molecules surrounds each ion in solution. Notice how the water molecules are oriented so that their dipole moments align with charges of the ions. The partially negative oxygen atoms of water molecules point toward Na cations, whereas the partially positive hydrogen atoms of water molecules point toward Cl" anions. 

The result indicating that the interface metal atoms in the supported clusters approximated as Rhe are charged, whereas those one layer removed from the support surface are not, leads to the question of the charge of the metal atoms in a flat metal raft. The issue has been addressed in experiments with y-Al203-supported clusters approximated well as Res, which were formed from H3Re3(CO)i2 [34]. The rhenium atoms were inferred on the basis of...
