LAG is particularly interesting for mechanochemical synthesis of porous frameworks and inclusion compounds, as the liquid can sometimes become incorporated into the final product as a guest and so direct (template) its structure. One example of mechanochemical formation of a metal-organic host-guest complex is the kneading of copper(II) chloride and dace in the presence of A,A-dimethylsulfoxide (DMSO) or water, which leads to the simultaneous in situ formation of the 1-D coordination polymer host [Cu(dace)Cl2] and molecular inclusion to form inclusion compounds such as [Cu(dace)Cl2] DMSO (Figure 2b). Importantly, the polymeric host itself is not obtainable by neat grinding... 

The connection between the phenomenological shell model (PSM) and aromaticity of metal clusters is presented in this chapter. This model allows us to probe the aromaticity of metal clusters, and also organic compounds, in a general framework and context. The 4n + 2 rule of planar rings is shown to be a special case of this model. It can be applied to the cases of planar, spherical, and distorted (oblate and prolate) clusters. The different criteria (stability, symmetry, magnetic properties, electronic structure) are considered with the examples of different scandium-doped copper clusters Cu c and Cu c+. In summary, a closed electronic structure according to the PSM often results in an aromatic behavior.
