摘要：

The di-nitrile complexes trans-[PtCl2(N CR)(2)] (R = Me, Ph, CH2Ph) react with an excess of gaseous NH3 in CH2Cl2 at -10 degrees C to form, in high yield, the corresponding di-amidine complexes trans-[PtCl(NH3){HN=C(NH2)R}(2)]Cl in which also one chlorine ligand has been displaced by NH3. The H-1 NMR spectra in DMSO showed the formation of different species which were characterized through NOESY, TOCSY and H-1/C-13 heteronuclear correlations as trans-[Pt(NH3){HN=C(NH2)R}(2)(DMSO)]Cl-2 and trans-[PtCl{HN=C(NH2)R}(2)(DMSO)]Cl.
