Tellurium-Bridged Silver Clusters

Although the synthesis of butylteUurolate-silver complexes requires low temperatures in order to avoid the precipitation of amorphous solids, and relatively few structural types of these compounds have been isolated (see above), the chemistry of phenyltellurolate-silver complexes from PhTeSiMc3 and AgCl is rich and varied with respect to the polynuclear frameworks formed. These aryltellurolate reagents can also 

Similar complexes can be prepared using the different phosphine ligands [PEt2Ph (118b) and PnPrj (118c)]. 

The growing interest in gold-chalcogenide polynuclear chemistry can be attributed partly to the demonstration that these systems exhibit rich photoluminescence behavior, and partly to the interesting structural frameworks that are generated as a result of weak Au(I)-Au(I) interactions [85].
