Structure and Bonding in Heteronuclear Gold Cluster Compounds

Structure and Bonding in Heteronuclear Gold Cluster Compounds 

The nature of the bonding in heteronuclear gold cluster compounds has been investigated primarily by means of semiempirical molecular orbital calculations and the results of these studies have allowed a number of structural generalizations to be made. These theoretical developments have been discussed in detail in a series of papers by Mingos et al. (210, 256, 279-282) and only a brief description of the results of this work will be given in this section. 

The frontier molecular orbitals of the AuPH3 fragment are shown in Fig. 34 along with those of other common transition metal fragments.

The occurrence of weak Au - Au interactions of this type gives rise to the possibility of alternative descriptions of the bonding in clusters
