Polymetallic dusters

Demonstration of tlie ctitical roles of tlie open conformations of polymetallic dusters bigliliglits tlieotetical analysis in cuprate diemistty. Polymetallic dusters in various s7iitlietic reactions ate ctitietiidy attracting tlie attention of syn-tlietic and medianistic diemists alike [40, 180-183]. 

The role of tbe additives, which may be used in bi- or muitnnetaltic combinations (Re, Ir, Ru, Ag, Au, Ge etc.) is poorly umterstood. They help to enhance the properties of platinum hy keeping it in a suitable state of dispersion, and to modulate the acidic character of the support. They appear to oppose the sintering of metallic crystallites by the formation of alloys or polymetallic dusters. 

Demonstration of the critical roles of the open conformations of polymetallic dusters highlights theoretical analysis in cuprate chemistry. Polymetallic dusters in various synthetic reactions are currently attracting the attention of synthetic and mechanistic chemists alike [40,180-183].
