Reaction of cis-[PtCl2(PPh3)2] with tetramethylthiourea (tmtu) in methanol under various conditions has been re-investigated. In the absence of base, the simple ligand substitution product [PtCl(tmtu)(PPh3)2]PF6 can be isolated by addition of excess NH4PF6. The complex was characterised by positive-ion ESI mass spectrometry, NMR spectroscopy and an X-ray structure determination. In refluxing methanol with excess Me3N, cis-[PtCl2(PPh3)2] reacts with tmtu to give a yellow solution containing the dinuclear monothiocarbamato complex [Pt2(mu-S){mu-SC(O)NMe2}(PPh3)4]+; the complex was isolated as BPh4- or PF6- salts. The X-ray structure of [Pt2(mu-S){mu-SC(O)NMe2}(PPh3)4]BPh4·CHCl3 is described. ESI mass spectrometry has been used to identify various reaction intermediates and by-products in the synthesis of [Pt2(mu-S){mu-SC(O)NMe2}(PPh3)4]+. [Pt2(mu-S){mu-SC(O)NMe2}(PPh3)4]+ acts as a metalloligand, e.g. towards PhHg+, but a pure product was unable to be isolated. DFT calculations suggest the presence of a Hg?O=C interaction.
