Favorable packing of the CO ligands about the cluster core was qualitatively and later (semi)quantitatively" investigated by Johnson et al. who, while searching for the best fit between the metal cluster and the optimum ligand polyhedron, eventually derived what is known as the Ligand Polyhedral Model (LPM). According to the LPM ... 

Exchange mechanisms can be postulated for these clusters involving the types of mechanisms reported for the binuclear complexes. However, it is more informative to consider the shape of the ligand polyhedron, as well as that of the circumscribed metal skeleton (71). For... 

It is useful to start the description of the electronic structure of a ligated metal cluster by separately considering the bare metal atom duster, with the exact same geometry as the metal core in the ligated duster, and the ligand polyhedron, as an empty spherical cavity, and then finally allowing the two parts to interact (Fig. M6).

The ambient temperature solution NMR spectra of the tris(dithiocarbamate) complexes, including those of Al (see above), show the complexes to be fluxional on the NMR chemical shift time scale. The stereodynamics can be quite complex with several different processes possible, namely, (1) a metal-centered rearrangement of the ligand polyhedron, (2) reversible ligand dissociation, (3) restricted rotation about the single N—C bonds of (bulky) N substituents.
