Reactions of the platinum(IV) nitrile complexes [PtCl4(RCN) 2] (R = Me, CH2Ph, Ph) with 1,2- and 1,4-PhS(=NH)C 6H4SPh in CH2Cl2 afforded addition products of sulfimides and coordinated nitriles, viz., the [PtCl 4{NH=C(R)N=S(Ph)(C6H4SPh)}2] complexes. The latter were isolated in 75-90% yielks and characterized by elemental analysis, positive-ion FAB mass spectrometry, IR spectroscopy, and 1H and 13C1H NMR spectroscopy. The temperature dependence of the 1H NMR spectra of the model [PtCl 4{NH=C(R)N=SPh2}2] complexes (R = Me, Et) in CD2Cl2 studied in a temperature range from +40 to -70°C demonstrated that E-Z isomerization of the ligands is a dynamic process in a range from +40 to -10°C. The activation free energy of this process was calculated.
