Abstract
The {[Pd(µ-SC6F5)(µ-dppm)Pd](µ-SC6F5)}4 (dppm = methanediylbis(diphenylphosphane)) (Pd8) metallacrown traps Ag(I) cations giving {Ag[Pd(µ3-SC6F5)(µ-dppm)Pd]4(µ-SC6F5)4}(X) (X = SO3CF3− (AgPd8a), SbF6− (AgPd8b) and ClO4− (AgPd8c)) and {Ag[Pd(µ3-SC6F5)(µ-dppm)Pd]4(µ-SC6F5)4}2[Pt(C6F5)4] (AgPd8d). The insertion of silver increases significantly the stability of the cluster that is stable in solution even in the presence of light, because of the macrocyclic effect.
