11Cluster compoun:ds11.1 lntroductionThe study of compounds which contain clusters of atoms, often ofhigh symmetry,is making significant contributions to theories of bonding. Part of the fascinationofthis area is aesthetic, deriving from the beautiful order which these structures,in their unanticipated variety, reveal. lmpetus for this work is enhanced by therealization that clusters, especially of transition metal atoms, may ha ve potentialas homogeneous catalysts, where two or more sites can act in conjunction.Moreover clusters sometimes ba ve tbe structures expected from fragments of tbeextended close packed arrays found in bulk metals. It bas tberefore beensuggested that tbey could provide a link between bomogeneous and beterogeneouscatalyst systems. Study of cluster cbemistry could possibly lead to a deeperunderstanding of the bebaviour of metal surfaces in catalysing reactions ofindustrial importance such as tbe reforming of bydrocarbons or conversions of'syntbesis gas'.11.2 Structure and bonding11.2 .1 Electron-precise structuresCarbon forms a wide range of catenated compounds linked togetber by strongC-C bonds. This property is sbared to a lesser extent by otber elements of tbesame Group (Si, Ge) and of adjacent Groups to tbe rigbt in tbe Periodic Table (P,As, S). The fragments CR 2 , PR and S ba ve 2 available orbitals whicb contain twoelectrons. Tbey can tbus link to form rings (CR 2 )", (PR)n, S" or chains withsuitable end groups. Tbe bonding in tbese 'clusters' can be described in terms ofclassical two-electron two-centre bonds. Tbese ring molecules are characterizedby a total of 6n valence electrons ( e.g. 4 from C and 2 from 2R) (Table 11.1 ).The fragment CH bas tbree available orbitals and tbree electrons for formingskeletal C-C bonds. Polybedral three dimensional structures can arise, some ofwhich are illustrated in Fig. 11.1. Tbe bonding in tbese ratber strained moleculescan again be described in classical terms. In ali eacb CH group contributes fivevalence electrons (four from C and one from H) so that a cluster (CH)" iscbaracterized by Sn valence electrons. Note tbat square and pentagonal as well as335
