Abstract:
1H,13C, and 195Pt NMR studies were performed for Pt(ll) and Pd(II) complexes with glycine cis- and trans-M(Gly)2, trans-Pd(GlyH)2Cl2 , cis- and trans-Pt(GlyH)2Cl2 , Na[Pd(GIy)Cl2], and K[Pt(Gly)CI2] in donor type solvents DMSO and H2O. It is shown that a cis ↔ trans equilibrium takes place in these solvents and that the equilibration rate is low for Pt(II) complexes and high for Pd(II) complexes. Therefore, the cis- and trans-complexes of Pt(II) may be recorded by NMR spectroscopy in the individual state, whereas for Pd(II) there is an equilibrium mixture of cis- and trans-isomers. Solvolysis of Cl-containing complexes in DMSO is studied. A mechanism of solvolysis involving cis ↔ trans isomerization of the dichloro complexes of Pd(II) is suggested. NMR spectral data for some solvolysis products are given.
