Two aqueous solutions of oxonitrocomplexes comprising di- and tetravalent platinum atoms, K5[(NO2)3PtIV(μ-O)3Pt 3 II (NO2)6]· 3H2O and K8[(NO2)6Pt 3 II (μ-O)3PtIV (μ-O)3Pt 3 II (NO2)6] · 7H2O, have been studied by195Pt and15N NMR technique. Both compounds, enriched with the15N (95%) isotope, were synthesized by thermal denitrozylation of K2[Pt(NO2)4]. Constants of spin-spin scalar coupling,195Pt-15N and195PtII-195PtIV, were obtained for tetra-and heptameric complexes in aqueous solutions through multiplet simulation. The195Pt and15N NMR spectra of the same solutions obtained two months after their preparation show signals from the hydrolytic forms of the tetrameric complex as well as the signals from mono- di- and trimeric oxonitrocomplex forms of divalent platinum. All signals of species formed as a result of hydrolysis were identified.
