Heteronuclear Clusters in Which No Ligands Are Attached to the Group IB Metals

HETERONUCLEAR CLUSTERS IN WHICH NO LIGANDS ARE ATTACHED TO THE GROUP IB METALS 

Most heteronuclear clusters in which no ligands are attached to the Group IB metals were prepared using one of the few generally applicable rational methods that are currently available for the synthesis of these species. These preparative routes all involve the addition of Ag+, either to preformed cluster anions (98,118,123,190,192) or to neutral polynuclear (188) or dimeric (189,191) compounds. Equations (66) and (67) show examples (189,190).
