Popis:	The metal-metal-bonded cations [Ag 2 Pt 3 (R 2 dtc) 6 ] 2+ , consisting of Pt(R 2 dtc) 2 units acting as ligands toward Ag(I), are observed in electrospray mass spectra as intact ions and also as the monoanion adducts [Ag 2 Pt 3 (R 2 dtc) 6 ] + (X-=ClO 4 -, NO 3- ). When solutions containing two different Pt(R 2 dtc) 2 complexes and Ag(I) are mixed, there is global scrambling of dithiocarbamate ligands on platinum in the Ag/Pt/R 2 dtc cations within 1 h, which is much faster than exchange in the absence of Ag(I)
