The role of anions in addressing the outcome of the reaction of tetramethylthiourea with cis-PtII(phos)2 moieties (phos = PPh3 or 1/2dppe), cyclometallation vs. hydrolysis to monothiocarbamato, and the crystal structure of trans-Bis(N- dimethylmonothiocarbamato)bis(triphenylphosphane)-platinum(II)

The product of the reaction between tetramethylthiourea (tmtu) and cis-PtII(phos)2 moieties (phos = PPh3, or 1/2 dppe) depends on the anionic species present. With NO3-, CF3CO2-, CF3SO3 -. and BF4-, the cyclometallate cationic complex [Pt(phos)2(tmtu*-C,S)]+ is obtained (tmtu* is tmtu deprotonated at one methyl group). The acetato and malonato complexes are inactive towards such deprotonation, but, in the presence of water, promote tmtu hydrolysis with formation of N-dimethylmonothiocarbamato (mtc) complexes in which mtc is S-coordinated. cis-[Pt(PPh3) 2(mtc)2] isomerises slowly to the trans isomer, whose crystal structure is reported.
