The aggregation states in solution of gold(I) cationic complexes of the formula [Au2(StBu)(L2)][BF4] (L = PMe3, PEt3, PtBu3, PPh3; L2 = dppm, dppe) were studied by MS (ESI) and DOSY spectroscopy. These compounds are tetranuclear in the solid state with a core of four gold centres bound together by aurophilic interactions and bridging thiolato groups. Some of these tetranuclear systems are maintained
