Abstract

Organometallic cluster compounds(1) with metal frameworks containing more than three metal atoms are similar to metal particles in having neighboring metal centers. These metal centers are chemically accommodated by appropriate ligand molecules such as carbonyls, phoshines, aryls, and halides. Some metal cluster compounds consist of frames having metal oxides and sulfide networks. As shown in Fig. 7.1, certain larger metal clusters such as \([R{{h}_{{13}}}{{(CO)}_{{24}}}{{H}^{{2 - }}}]\), \([P{{t}_{{19}}}(CO)_{{22}}^{{4 - }}]\), and Rh55(PPh3)12Cl6 have structures very much like the closest-packed metal atoms in small metal crystallites which are found in some industrially useful metal catalysts.KeywordsMetal ClusterCarbonyl ClusterButane ConversionMetal Carbonyl ClusterMetal Cluster CompoundThese keywords were added by machine and not by the authors. This process is experimental and the keywords may be updated as the learning algorithm improves.
