Reaction of RNHC(S)PPh2NPPh2C(S)NR (HRSNS; R = Me, Et) with Ml (M = Cu, Ag, Au) salts afforded zwitterionic complexes of the general formula [M(RSNS)] (M = Cu, Ag, Au). The ligand was found in the solid state in S,S-k² and S,N,S-k³ coordination fashions. [Cu(RSNS)] and [Ag(RSNS)] can be used as metalloligand building blocks for the assembly of pentanuclear multizwitterionic Cu5, Cu3Ag2 and Ag5 core clusters of the general formula [M′2{M(RSNS)}3]2+ (M = Cu, M′ = Cu, Ag; M = M′ = Ag) upon reaction with suitable M′ salts. The crystal structures of the most significant compounds are reported herein. Compound [Ag2{Ag(RSNS)}2(OTf)2] was also isolated and structurally characterized, representing a model for the intermediate species of the aforementioned assembly. [ABSTRACT FROM AUTHOR]
